叶肥“稻多收”在水稻上的增产效果

Effect of Foliar Application of Daoduoshou on Rice Yield Increase

进行了叶肥“稻多收”在水稻不同季别、不同品种上使用的试验示范。结果表明 :叶肥“稻多收”具有增绿、增穗、增粒、增重等功效 ,只需在抽穗期喷施 1次 ,可增产稻谷 10 %～ 2 0 %。试验示范了 60 .67hm2 ,平均增产稻谷 75 3kg/hm2 ,共多收稻谷45 682kg。

Foliar application of Daoduoshou in rice plants had the multiple functions including the increase of leaf-chlorophyll content,number of spikes and full-grains and 1?000 seed-weight.The yield increase generally amounted to 10%～20% with only once application at spike stage.In demonstration of about 60.67?hm 2 in Xuanzhou city in 2001,the average increase of grain-yield was tested to be 753 kg/ hm 2,the total grain-yield increase amounted to 45?682?kg.
