近年来,一些地区绿肥种植面积因复种指数的不断提高而逐年减少,致使土壤肥力逐年下降。我们建议今年秋播各地要因地制宜,适当恢复绿肥种植, 积极推广菜肥兼用、一肥多用的经济绿肥,千万百计套播好棉田冬绿肥。及早备种一般棉田套种,苕子每亩备种2-3公斤;大荚箭豌、百花豌豆每亩3-4公斤;蚕豆每亩13公斤;黄花苜蓿每亩8-10公斤;黑麦草每亩0.5公斤。播前坚持晒种,以提高发芽率。
In recent years, the planting area of green manure in some areas has decreased year by year due to the continuous improvement of the multiple cropping index, resulting in a year-by-year decline in soil fertility. We suggest that we should adjust measures to local conditions for autumn planting this year, restore green manures as appropriate, actively promote the use of both vegetable and fertilizer, and use more economical green manures. Early preparation of general cotton field intercropping, prickly heat preparation of 2-3 kg per acre; large pods peas, peas flowers 3-4 kg per acre; beans per acre 13 kg; alfalfa 8-10 kg per acre; rye grass Mu 0.5 kg. Spread the sun before planting, in order to improve the germination rate.
