耕作质量的好坏,直接影响着土壤保水、保肥能力及作物对养分的利用。为切实做到既用地又养肥,我采用了秸秆盖田耘地耕作法。经1980—1983年4年的田间试验证明,应用秸秆盖田耘地耕作法,作物当季可增产4%。后季增产13%。并可节省油、水(电)和人畜力以及机械油耗等。此措施现已在滕县推广千亩以上,均取得较好的效益。一、基本情况试验田为河潮土,有机质含量为0.81%,全氮为0.91%,速效磷13.5ppm,速效钾62ppm。试验设秸秆盖田耘地种植和对照(常规耕翻施肥处理两种。
Tillage quality is good or bad, a direct impact on the soil water, fertilizer and crop nutrients use. In order to effectively achieve both land and fat, I used the straw cover Tian Yun to farming methods. Four years from 1980 to 1983, field trials proved that the application of straw mulch tillage farming methods, crop season can increase 4%. The latter quarter increased by 13%. And can save oil, water (electricity) and human and animal power and mechanical fuel consumption. This measure is now more than acres in the promotion of Tengxian, have achieved better results. First, the basic situation Experimental field for river moisture, organic matter content of 0.81%, total nitrogen was 0.91%, available phosphorus 13.5ppm, available potassium 62ppm. The experiment set straw cover Tian Yun planting and control (conventional tillage fertilizer treatment two.
