为解决板栗树体负载量问题,我们于1980—1982年进行了板栗疏棚试验。一、试材和方法试验在栖霞县杨础大队进行。试验地为等高梯田,活土层36厘米,pH6.5。试材为1978年嫁接的结果幼树。树体状况基本一致。7月中旬疏棚,方法是:强果枝一般留棚3个,中庸果枝留2个,弱果枝留1个。采收时统计成棚数、栗实数和粒重。二、结果与分析试验结果(附表)表明,疏棚,无论成棚率或结实率都比对照高。单粒重除个别不疏棚的粒大以
In order to solve the chestnut tree load problem, we carried out the chestnut shed experiment in 1980-1982. First, the test materials and methods Tests in Qixia County, Yang based brigade. Test for the contour terraces, living soil 36 cm, pH6.5. The test material is the result of grafting in 1978 young trees. Tree body condition is basically the same. In mid-July canopy, the method is: strong fruiting branches generally stay shed 3, moderate fruit stay 2, weak fruit stay 1. Harvested harvest statistics into shedding, chestnut number and grain weight. Second, the results and analysis The test results (Schedule) show that the canopy, regardless of the shed shedding rate or seed setting rate than the control. Single grain weight is not the only exception, the large grain
