| titleOfInvention | A kind of production method of double cropping rice joint nitrogen high yield |
| abstract | The present invention selects double cropping rice growing area, before late rice results, within 15-30 days, carry out Chinese milk vetch sowing, after late rice results, hold ditch successfully by Chinese milk vetch planting technology, execute fused calcium magnesium phosphate 30-50kg/ mu, potassium chloride 1-2kg/ mu makees base manure, and early rice transplants front 10-15 days, carries out non watered ploughing and turns over, by early rice planting requirement wholely, put red duckweed in a suitable place to breed, after keeping shallow water 8-10 days of field water 1.5-3.5cm height, basal dressing carries out early rice transplanting.Early, late rice growing period naturally fall duckweed, before late rice transplanting, slow Controlled Release Nitrogen Fertilizer does base and executes disposable applying, mid or late September next year carries out the cycling of the farming such as Chinese milk vetch green manure crop plantation, Chinese milk vetch green manure is planted during the winter slack that the present invention is planted by double cropping rice, red duckweed is put in a suitable place to breed during paddy growth, the special slow Controlled Release Nitrogen Fertilizer of late rice reducing application amount paddy rice, utilize Chinese milk vetch and red duckweed fixed nitrogen, inhale carbon, increase soil fertility with ground, for paddy rice provides organic materials and organic nitrogen source, absorb the nutrient easily run off in double cropping rice rice field, reduce pollution of area source, fertilizer and paddy rice are needed fertile harmonious. |
