为了摸清红萍的肥效及其增产效果,我们于一九七九年三月配合上涌公社云路大队第三生产队(海拔700多公尺),进行养萍肥田对比试验。试验分三个处理,一个对照。具体的处理方案是每亩稻田:压鲜萍3300斤;施腐熟牛粪2500斤;施碳铵50斤;无施基肥作对照区。每个处理面积为0.02亩。红萍区系将鲜萍压埋入土肥田。供试品种为杂交水稻“四优二号”。试验小区采用互比排列,重复一次。每个小区都有一个进水口和出水口,单独排灌。小区追肥的肥料种类用量,施用方法,数量比例与大田相同。四月十九日播种,湿润育秧,按照杂交水稻的要求培育壮秧,秧龄45天,秧苗粗壮,一般都有3～4个分蘖。本田五月二十六日耙田,六月一日细耙作小区,然后按试
In order to find out the effect of Hongping and its yield increase, we cooperated with the third production team of Yunlu Brigade of Shangyong Commune in March 1979 (more than 700 meters above sea level) to carry out the comparative experiment of raising fertilizer and fertilizer. The test is divided into three treatment, a control. Specific treatment program is per acre paddy: pressure Xianping 3300 pounds; applied maturity 2500 cattle manure; carbon ammonium fertilizer 50 pounds; no base fertilizer for the control area. Each treatment area of 0.02 acres. Hongping district will be pressed into fresh soil pressure soil fertilizer field. Test varieties for the hybrid rice “four excellent two.” The test plot is arranged one above another and repeated. Each district has a water inlet and outlet, irrigation and drainage alone. Area fertilizer top-dressing fertilizer types, application methods, the number of the same proportion and field. April 19 sowing, wet nursery seedlings, in accordance with the requirements of hybrid rice nurturing strong seedling, seedling age 45 days, stout seedlings, usually have 3 to 4 tillers. Honda harrowed on May 26, June harrow for plot area, and then try
