为获取高产优质,花生约需4—5个月的生长期,偏高和适中的温度,在其生育期中约500毫米的良好雨量分配。在播种时降雨良好有利于出苗和保苗,而生长季内雨量分配良好可确保植株营养生长良好,增进开花和荚果的发育。从花形成到开花期间充足的水分尤为重要。大量持续降雨条件下,由于营养生长过旺,会导致减产和延长生长期。收获和干燥过程中,干旱条件有利。
To achieve high yield and good quality, peanuts require about 4-5 months of growing season, high and moderate temperature, and good rainfall distribution of about 500 mm during their growth period. Good rains during sowing are good for emergence and seedling preservation, and good rains are distributed well throughout the growing season to ensure good vegetative growth and increased flowering and pod development. It is especially important to form ample water from flower formation to flowering. Under a lot of continuous rainfall, due to overgrowth of nutrition, it will lead to the reduction of production and the prolongation of growth period. Drought conditions are favorable during harvesting and drying.
