Return Milk vetch

Red flowers, the scientific name of Chinese Milk vetch, rice has a tradition of thousands of years of history, China is green manure in Anhui acreage has grown from 60 ~ 70 's of last century peak of more than 16 million acres, down 2 million acres now, only 3% per cent of arable land. Since the early 80 's, due to the adjustment of agricultural structure and a large supply of chemical fertilizer, the low in yields direct benefits of planting green manure crops, causing farmers to reuse light light yangdi, heavy fertilizer organic fertilizer, light current interest long-term interests is particularly prominent. The past 30 years, due to the heavy use of chemical fertilizers, manure production line reduced the sudden landslide soil fertility. Born of the 670 people who grew up in the countryside, often such a sigh: bright, colorful food fruit and vegetables in the supermarket and ate it without the delicious taste of childhood memories. Because of heavy use of chemical fertilizers increased pollution, and land as a result of compaction soil fertility decline, especially as the four soil nutrients (organic matter, nitrogen, phosphorus, potassium), head of the organic matter of extreme lack of overdraft and direct impact on land productivity and the quality of agricultural products. According to testing, soil organic matter content in the 3%~5% down to 1%, and continues to decline. Now, whenever we roll up our pants at the foot in the paddy field, soft legs caked with black mud of the past is gone, soles of the feet reflect feelings is the compaction of the soil hardening rough, as if feel that thin body of mother earth. On soil organic matter necessary complement in a timely manner, just like breast-feeding mother needs to supplement essential nutrients without delay. Now, farmers to grow crops such as rice, most rely on ever-increasing chemical fertilizer increase production, treat milk like mother used drugs to stimulate the pursuit of milk, water, and failed to consolidate sources of nutritional supplements, leading to health of its low and declining quality of milk produced by.

How nurturing mother earth creatures extreme physical infirmity to recuperate breath? now, with regression function of ecological civilization cycle agriculture advocacy and national soil organic matter to improve the project guide, output decreased in land under force, large red flowers and return the fields in full bloom.

Plant green manure full of treasure

Proverb: flowers with three years, thin cover. Why the red flowers have the ability? the majority of rural South, entering every year in September, clover intercropping with rice. Late in April next year, red flowers after blooming, which is plowed into the ground. Farmers then water retting, 7-10 days after transplant seedlings. Effect of safflower grass fertilizer to enrich soil nutrients, soil physical properties and increase crop yields, and purify the air to beautify the environment. Safflower grass soil improvement works because plants absorb carbon dioxide and nitrogen in the air, through the effective carbon and nitrogen fixation of rhizobia in the soil and greatly improve the water, soil fertility, air micro-environment. Green manure has strong roots to the soil interspersed with compression, the permeability of the soil increased. Now planted an acre of red flowers, fresh grass yield of up to 2000 kg, containing 10% of organic matter, equivalent to provide 200 kilograms of organic matter for the soil layer and per hundred kilograms of fresh grass can provide 0.5 kg of nitrogen to the soil. After calculation, red flowers containing nitrogen, phosphorus, potassium, zinc, manganese, and other nutrients, lasting and stable fertility, planting safflower grass, fertilizer can be reduced by 40%, after the kind of soil fertility in two to three years to significantly improve. Especially with green manure for effects, relative Yu traditional animal stool, manure more health clean, no heavy metal, and antibiotics, and hormone, residues threat, in some area even became organic agricultural only manure, for promote rice field balance meaning major: due to from plant of biological sex fertility can significantly increased crop resistance gene, makes fertilizer pesticide herbicide of reduction volume disappeared, let paddy in of Loach, and eel, and small crab, and frog, and snail, and water snake, gradually return, rice tree between eat insect of Sparrow, and gray magpie, and Pulsatilla came, natural biological control of effectively maintaining the biodiversity of nature balance.

Chinese Milk vetch was a treasure, also has the function of selenium-enriched soil, in front of the Chinese Milk vetch flowers, harvest above middle of plant shoot apex, into SE-rich dried vegetables, delicious and high prices. Tongcheng city, Anhui Province, farmers in the agricultural sector and cooperative economic organizations of selenium-rich tea, selenium-dietary fibre and other products the exploitation of results is outstanding. Anhui, susong Guide to pig farmers use Astragalus fresh grass for animal feed, meat quality, market prices higher than 4 Yuan/kg of pork, a pig can be an additional 200 Yuan. In addition, the well-known Chinese Milk vetch honey and pollen are China's traditional export products, clover honey 10 kg per MU, eye-opening high nutritional value. Clover flower up to 30-40 days, continuous burst, and replaced by the brilliant Chinese Milk vetch flowers Golden rape flowers landscape, not only can relieve great pressure on the city year afternoon straw burn-ban, increase the oxygen content in air purification air, but also as urban eco-tourism and leisure are added with a beautiful landscape. That is why, in order to enhance confidence in farmers planting of large numbers of Chinese Milk vetch, some districts of Hefei city takeover agreement with the fengle seeds industry, is responsible for the recovery of Hefei city, 30,000 acres of Chinese Milk vetch seed. For large scale farmers in the planting of Chinese Milk vetch, Hefei municipal Committee of agriculture subsidies give 100 yuan per Mu each year.

It was reported that Zhu Xi town, xianju County, Zhejiang Province, Green warehouse cooperatives, 4 years today to promote "green manure cleaned rice" more than 30,000 acres, the production of "green manure in rice" price of 20 Yuan per kg, per Mu net profit for 2000. 62, Nan County, Hunan province, San Xian Hu Zhen Chen Guanghua Wan Village, 25 acres of planted 8 years in a row of green manure in winter fallow land. Green manure crop prior to project implementation, Chen's early and late season rice yield only 700 kg. Since 2008 to participate in the pilot after green manure production year after year, two more than 900 kg rice per MU on average. In Chen's view, species of astragalus, there are five major benefits: one is to use less fertilizer, second, weed dilute, three soil is loose, four is the maturity balance of rice, five is the increase in yield. It can be seen that not only reduce the cost of comprehensive utilization of green manure planting and agricultural product quality, also by yangdi sustainable utilization farmland fertile soil to benefit future generations, to achieve "efficiency, product safety, resource-saving and environment-friendly."

A prairie fire to save the Earth

Since safflower grass is a treasure, promotion can has what difficulty? Anhui Province agriculture for green manure research stagnation years, led to green manure varieties mixed degradation production declined, and planting using technology integrated insufficient of status, skillfully take national implementation arable land quality protection and upgrade action of Dongfeng, big area implementation green manure planting upgrade ecological agricultural quality, through funds Guide, and technology model, means, go cycle using of road. Starting from 2007, Anhui Academy form Wang Yunqing green manure team of researchers for the principal, in Xindian village, Lv Ting, Tongcheng town established the first clover planting area, have been developing Anhui violet 2nd, Chinese Milk vetch, yijiang, Yu Jiang leaves series varieties. Flower prairie violet, jianghuai, now distributed in several clover test area along the Changjiang River with a total area has reached 2 million acres. Since 2008, the Anhui Province agriculture in nanling, and Jing County, jingde, and ningguo Tongcheng,, and, and, and the huaining, and Taihu, susong, Jin an 9 County area o enhance the yield of green manure crop planting projects, projects to provide free seeds, inoculants, training, popular with farmers. Tongcheng, susong Chinese Milk vetch planting green manure area of 560,000 acres before the commencement of the project to the current 100,000 acres, fresh grass yield increased from project pre-1500 kg/Mu more than 2500 kg/acre. As early as 1996, zongyang allocated 80,000 yuan from relief funds, for the development of Chinese Milk vetch in the production Fund, transferred to 2 tons of local varieties "yijiang seed" in 5 towns for 3 consecutive years, breeding, form a large complex, with self-contained new situation, now the County's Milk vetch to 180,000 acres of area development.

Needless to say, food security and ecological security on the Chinese population the importance of urgency is self-evident. In today's urbanization process, strengthening infrastructure construction, industrial pollution, huge pressure on arable land situation, making good use of our existing land on which it is particularly urgent. To let Milk vetch prairie fire everywhere, industry people calls for, on Anhui (4.8 million acres) and national in deserted State of seasonal winter field, should quickly established winter field idle punishment mechanism, will encourages and support farmers widely planting safflower grass, green manure crops as achieved agricultural sustainable development strategy of important hand to implementation, increased green manure seed subsidies efforts, gradually implementation free supply seed, and free technology training and guide service,, guide professional cooperatives carried out green manure unified production, and for species, and sowing, and management, and Turn pressure and other social services, expanded integration demonstration effect, attract increased individual productivity, make Milk vetch ornament green and thousands of families off the dream.
