钾肥通常用做基肥或早期追肥.1984年为了探讨氯化钾溶液浸种是否能为秧苗提供钾源,在建宁县农科所的田块进行了试验.试验选用光红品种,分别用清水、1%、5%、10%浓度的氯化钾溶液浸种60小时,清水洗净后在恒温32℃下催芽48小时.试验田选肥力中等的黄底灰泥田,含速效钾142.5ppm、有机质2.4%.3月24日播种,秧田在二叶期揭膜炼苗,揭膜3天后亩施尿素10斤.
Potash fertilizer is usually used as basal fertilizer or early top dressing .In 1984, in order to explore whether potassium chloride solution could provide potassium source for seedling, Jianning County Agricultural Science field plots were tested using light red varieties, respectively, with water, 1 Potassium chloride solution of%, 5%, 10% was soaked for 60 hours, washed with water and incubated for 48 hours at a constant temperature of 32 DEG C. The yellow paddy field with medium-available potassium fertilizer was 142.5ppm with 2.4% of organic matter. March 24 sowing, seedling shed in the second leaf Lian Miao Miao, exposing film 3 days after the implementation of urea 10 pounds.
