自1990年以来,我们连续作了KH—841型保水剂对小麦出苗、生长、及产量影响的试验,证明在小麦播种时用保水剂预处理种子,能促进种子早萌发,促进幼苗发育,提高产量,经济效益显著。现简要介绍如下: 一、试验材料及处理 1.试验用小麦品种为875、872及狼尾麦等。保水剂为KH—841,由北京化工厂提供。试验地为中等或中下等肥力,沙土、沙壤土、轻壤土、粘土均有。
Since 1990, we have consecutively made experiments on the effects of KH-841 water-retaining agent on emergence, growth and yield of wheat. It is proved that pre-treatment of seed with water-retaining agent in wheat sowing can promote early germination of seed, promote seedling development and increase Output, significant economic benefits. Now briefly introduced as follows: First, the test materials and processing 1. Test wheat varieties 875,872 and wolf tail wheat. Water retaining agent for the KH-841, provided by the Beijing Chemical Plant. Test medium or medium and low fertility, sand, sandy loam, light loam, clay.
