1施足基肥,提高整地质量花生播种前,深耕深翻,施足基肥,施土杂肥4.5万kg/hm2,复合肥750kg/hm2,石灰粉或石膏粉600kg/hm2,硼砂15kg/hm2,硫酸锌15kg/hm2,撒施药剂防治地下害虫。然后耙匀耙平,保证地面平整,地表没有秸秆、坷垃、石块等杂物。2足墒播种实行足墒播种,保证土壤相对含水量在75%以上播种。黄淮海地区春季十年九旱,一般4月中下旬因冷暖气团在该地区交汇而有1~2次降水过程。五六月份气温升到20℃,降水带南移,该地区降水量较少。春季雨后花生适播期只有3~4d,因此,4月中旬以后,只要有自然降水,土壤墒情适宜花生播种,就要抢墒播种花生。
1 Application of sufficient base fertilizer to improve the quality of land preparation Peanut before sowing, deep plowing deep conversion, application of foot fertilizer, Shi Tuzafei 4.5 million kg / hm2, compound fertilizer 750kg / hm2, lime or gypsum powder 600kg / hm2, borax 15kg / hm2, Zinc sulfate 15kg / hm2, spraying pesticides to control underground pests. Then rake flat rake, to ensure the ground level, the surface without straw, builders, stones and other debris. 2 enough soil moisture sowing implementation of planting moisture to ensure that the relative soil moisture content of more than 75% of sowing. Huanghuaihai nine spring drought ten years, usually in late April due to cold and warm air mass convergence in the region and have 1 or 2 precipitation process. May and June temperatures rose to 20 ℃, south of precipitation, precipitation in the region less. After spring rains, the sowing date of peanuts is only 3-4 days. Therefore, after mid-April, as long as there is natural precipitation and soil moisture is suitable for planting peanuts, it is necessary to grab moisture to sow peanuts.
