近年来,我县农村广大干群在科学实验的实践中,充分利用土地和季节,在棉田中套种春绿肥箭舌豌豆、保豌一号,夏绿肥绿豆、田菁、芝麻等,掩青作棉花当家肥。实践证明,棉田套种春夏绿肥,是一种投资小,花工少,见效快,自力更生增辟肥源的新途径,是培肥土壤,促进棉花增产的有效措施。一、套种春夏绿肥对棉花的增产效果棉田套种春夏绿肥掩青的皮棉产量较未套绿肥的增产三至五成以上,平均增产48.9%,每亩净增皮棉31.4—57.9斤,平均43.9斤。每百斤绿肥可增产皮棉3.43
In recent years, the majority of cadres and rural cadres in rural areas in the practice of scientific experiments, make full use of the land and the season, in the cotton field intercropping spring green fat tongue tongue pea, Paul pea, summer green manure mung bean, Sesbania, sesame seeds, Cotton is fat. Practice has proved that intercropping cotton spring and summer green manure is a small investment, less artificial, effective, self-reliance and new sources of fertilizers a new way is to fertilize the soil and promote cotton yield an effective measure. First, intercropping spring and summer green manure on the yield of cotton cotton intercropping spring and summer green manure cover the lint yield than the unmanaged green manure increase of more than three to five percent, an average yield of 48.9% per mu net lint 31.4-57.9 kg, an average of 43.9 jin. Per kg of green manure can increase lint 3.43
