中稻和双孢蘑菇轮作效益研究

目的]研究中稻和双孢蘑菇轮作的效益。方法]通过2014—2016年连续3年中稻和双孢蘑菇轮作试验,研究中稻和双孢蘑菇轮作产生的经济效益和生态效益。结果]中稻和双孢蘑菇轮作收到了较好的经济效益:纯收入30万~50万元/(hm2·a),是单纯栽培中稻的10多倍,经济效益主要来源于双孢蘑菇栽培。中稻和双孢蘑菇轮作有效改善了稻田土壤肥力和基本理化性质,提高了土壤有效NPK含量和有机质含量。结论]中稻和双孢蘑菇轮作生产措施简单粗放,省工省时,适合大面积推广。

Benefit Study of the Rotation of Middle-season Rice and Button Mushroom

Objective] To study benefit of the rotation of middle-season rice and button mushroom.Method] Through three continuous test of the rotation of middle-season rice and button mushroom during 2014-2016,economic benefits,ecological benefits that produced by the rotation of middle-season rice and button mushroom were studied.Result] The rotation of middle-season rice and button mushroom had received the good economic benefit:the net income was 30 0000-50 0000 yuan/(hm2 · a),which was more than 10 times of cultivated rice,economic efficiency mainly came from button mushroom cultivation.The soil fertility and the basic physicochemical properties of rice paddies were effectively improved by the rotation of middle-season rice and button mushroom,which improved the effective NPK content of soil and increased organic matter content.Conclusion] Tbe production measures of middle-season rice and button mushroom rotation are simple and rough,which is suitable for large-scale promotion.
