有机肥多作为基肥施用,而春季施肥以春播或春季移栽作物为主,所以合理施用有机肥就更加重要。有机肥在备肥和施用时要注意以下几点:施肥前一定要堆沤。有机肥中的养分多为无效态,难以被作物直接吸收利用,必须在腐熟过程中通过微生物分解转化变成有效态;有机肥中含有各种有害的病菌、虫卵和草籽,必需借助腐熟发酵的高温进行杀灭。不少种植大户将有机肥事先腐熟后封堆保存,隔年再用,这是一个成功的经验,应予以推广。因作物而异,掌握好施肥量。有机肥与化肥各有所长和不足,两者要配合施用。考虑到合理性和可能
Organic fertilizer and more as a base fertilizer application, and spring fertilization in spring or spring transplanting crops, so the rational use of organic fertilizer is even more important. Organic fertilizer in the preparation of fertilizer and application should pay attention to the following points: Fertilizer must be piled up before. Organic nutrients are mostly inactive state, it is difficult to be directly absorbed by the crop must be decomposed and transformed into an effective state in the decomposing process; organic fertilizer contains a variety of harmful germs, eggs and seeds, the need to decompose High temperature fermentation to kill. Many large planted farmers will be pre-matured organic fertilizer confined to save the pile, reuse next year, this is a successful experience should be promoted. Depending on the crop, master the amount of fertilizer. Organic fertilizer and fertilizer have their own strengths and weaknesses, both with the application. Take into account the reasonableness and possibility
