为探讨深耕改土对玉米的增产效果,榜墟公社福吉大队吉元三队等三个队的农科组进行了深耕改土试验,在同一块(或一垌)地的土壤类型、肥力大致相同的条件下,分别采取深耕改土,只深耕不改土和不深耕不改土等三种不同处理,以后一种处理作为对照。深耕改土做法是在玉米播种前,按玉米双行单株的播种规格,在玉米播种行里挖沟深0.8—1尺,宽1.5—2尺,然后每亩加客土800—1000
In order to discuss the effect of cultivating soil on the yield increase of maize, the agro-science team of the three teams, the Fudge Brigade of the Fubi Brigade of the Kuan Hui Commune, conducted the plowing and soil improvement experiments. The soil types and fertility in the same block (or 垌 垌) were roughly the same Under the conditions, respectively, to take deep plowing and earth improvement, only deep plowing do not change soil and not plowing does not change the soil three different treatments, a treatment as a control.
