花生花针期根系发育迅速,茎叶生长旺盛,营养生长与生殖生长接近,主攻目标是:促进根系发育,茎叶稳健生长,争取花多,针多。具体措施如下:1.中耕培土。花针期应及时深中耕,松土除草,培土迎针。培土时间要适宜,在植株尚未封行前低节位,茎伸长的果针入土厚,单株盛花期时培土最适宜。过早,过晚效果都不好。2.追肥。花生中期是需肥最高时期,一般亩施标准氮5—8公斤,缺磷地块可每亩施过磷酸钙10公斤,缺钾时可
Peanut flower needle root system developed rapidly, vigorous growth of stems and leaves, vegetative growth and reproductive growth close, the main goal is: to promote root development, stems and leaves steady growth, to spend more flowers, needles and more. Specific measures are as follows: 1. Cultivated soil. Squashing should be timely deep plowing, loosening and weeding, planting soil welcome needle. Soil preparation time should be appropriate, in the plant has not sealed line low node, the stem elongation of the needle into the soil thick, single flowering plant when the most appropriate soil. Premature, late effect is not good. 2 top-dressing Peanut mid-term is the period of the greatest need fertilizer, the general standard nitrogen 5-8 kg Mushi, phosphorus-deficient plots can be applied per kilogram of calcium phosphate 10 kg, potassium can be
