1.种植绿肥有利于提高果园土壤的养分含量。绿肥是一种完全的生物肥源,据有关资料表明,绿肥鲜草含有机质10％～20％,按鲜草每亩产150公斤计算,可提供有机质150～300公斤,相当于增加土壤有机质含量0.3％。绿肥作物的根系发达,能利用深层中的养分,吸收难溶性养分的能力较强,使难溶性养分转变为有机态养分,起了集中深层养分于耕层及提高难溶性养分有效性的作用。种植绿肥既节省化肥投入又节省运肥投工。
1. Planting green manure helps to improve the nutrient content of the orchard soil. Green manure is a complete bio-fertilizer source, according to the information shows that fresh green manure contains 10% to 20% of organic matter, according to 150 kg per mu yield of fresh grass, organic matter can provide 150 to 300 kg, equivalent to increase soil organic matter content 0.3%. The root system of green manure crops is developed. It can utilize nutrients in deep layers and has strong ability to absorb insoluble nutrients. It turns insoluble nutrients into organic nutrients and plays a role in concentrating deep nutrients in tillage layers and improving the availability of insoluble nutrients. Planting green manure saves both fertilizer and fertilizer operation.
