CB-1施硼量与施镁量互助研究

Cooperative Study on B Fertilizer Amount and Mg Fertilizer Amount of CB-1

2012年在建阳市莒口镇莒口村进行了CB-1的施硼量与施镁量互助研究,结果表明:各处理烟株在生育进程及大田生育期上差别不大,农艺性状表现较优的有处理B2M2、B3M2、B3M3,产值效益较高的处理有B2M1、B2M2、B3M3。综合分析,施硼量和施镁量配合较优的处理为B2M2(施硼7.5 kg/hm2,施氢氧化镁75 kg/hm2),B3M2(施硼15 kg/hm2,施氢氧化镁75 kg/hm2),B3M3(施硼15 kg/hm2,施氢氧化镁150 kg/hm2)。

A cooperative study on B fertilizer amount and Mg fertilizer amount of CB-1 was conducted in Jukou Village of Jianyang City in 2012. The results showed that processed tobaccos did not manifest many differences in the development progress and the growth duration after transplanting. The treatments which led to better agronomic trait performance were B2M2,B3M2,B3M3,while the treatments that had high output values were B2MI, B2M2, B3M3.After the comprehensive analysis, we drew the conclusion that the optimum treatments of B and Mg proportion were B2M2 （B fertilizer amount per hectare ： 7.5 kg, Mg fertilizer amount per hectare ： 75 kg）, B3M2 （B fertilizer amount per hectare ： 15 kg, Mg fertilizer amount per hectare ： 75 kg）, B3M3 （B fertilizer amount per hectare ： 15 kg, Mg fertilizer amount per hectare ： 150 kg ）.
