我省自五十年代开始大力发展双季稻、推广肥、稻、稻耕作制以来,农业生产有了较大的发展。但是,由于长期实行双季稻、绿肥和双季稻冬作三熟制,土壤浸水时间长,没有晒垡炕土的机会,土壤结构遭到破坏。不仅耕层土壤板结,耕性不良,土壤通透性差、性状恶化,而且土壤肥力下降,病虫、草害严重,生产投工、投资增加,影响粮食持续增产;同时由于片面发展水稻,压缩饲料作物种植面积,造成饲料短缺,又影响了畜牧业的发展。为了解决这些问题,
Since the 1950s, the province has made great efforts to develop double cropping rice, and has promoted the development of fertilizer, rice and rice farming since its development. However, due to the long-term implementation of double cropping rice, green manure and double cropping rice in winter, the soil has been damaged for a long time without immersion of kang soil. Not only tillage soil compaction, poor tillage, poor soil permeability, traits deterioration, and soil fertility decline, pests and diseases, grass and grasses serious production and investment, affecting the continued increase of grain production; the same time due to unilateral development of rice, compressed feed crops Planting area, resulting in feed shortages, but also affected the development of animal husbandry. In order to solve these problems,
