在发达的农业中,产量的显著提高主要是在提高土壤肥力的基础上,综合采用其它农业科技成果的结果.根据我国的国情、农情和生态环境,走无机农业的道路是难以行通的,当前解决肥料问题的立足点还得放在有机肥上,走有机与无机相结合的道路.但人多地少,多种绿肥又有困难,我们设想,用30%的耕地种绿肥,依据绿肥的生物学特性,采用相应的技术措
In developed agriculture, the significant increase in output is mainly based on the results of other agricultural scientific and technological achievements based on the improvement of soil fertility, and according to China’s national conditions, agro-ecological and ecological environment, it is difficult to follow the path of inorganic agriculture At present, the standpoint of solving the fertilizer problem has to be put on the organic fertilizer, taking the path of organic and inorganic combination.But more people are less, and there are many kinds of green manure which are difficult. We assume that 30% Green manure biological characteristics, the use of appropriate technical measures
