为探索板栗幼树早实丰产栽培技术,1976年以来,我们在五圣公社周庄大队的协作下开展了这项试验研究工作。试验地设在周庄大队,面积2.049亩。为河滩小平地,沙质壤土,土深1米,pH值5.9。可以自流灌溉。1976年4月定植5—7年生实生苗作砧树。分两片定植:一片0.964亩,株行距2×1.5米,共栽210株(以下简称甲片);一片1.085亩,株行距2×3米,共栽120株(以下简称乙片)。栽后进行嫁接。接穗采自山东省果树研究所,主要品种是:青毛软刺、广西
In order to explore early chestnut sapling high yield cultivation techniques, since 1976, we in the five Holy Communities Zhouzhuang brigade in collaboration with the pilot study. Experimental site located in Zhouzhuang brigade, an area of 2.049 acres. For a small beach, sandy loam, soil depth of 1 meter, pH 5.9. Can self-flow irrigation. April 1976 planted 5-7-year-old seedlings as an anvil tree. It is planted in two pieces: one piece of 0.964 mu and the line spacing of 2 × 1.5 meters, a total of 210 plants (hereinafter referred to as the A piece); a piece of 1.085 mu, the line spacing of 2 × 3 meters, a total of 120 plants (hereinafter referred to as piece B). After planting grafting. Scion from Shandong Institute of Pomology, the main varieties are: green hair soft thorn, Guangxi
