随着农田复种指数逐年提高,土壤中的钾被作物带走的越来越多,土壤缺钾已成为作物高产的重要障碍因子之一。但是,目前商品钾肥供应短缺,为了稳步提高农作物产品和质量,积极开发和合理利用农家钾肥资源就显得十分重要。 1、科学贮用草木灰。草木灰是重要的农家钾肥,一般含钾5—8％,50公斤草木灰即相当于5—6公斤氯化钾。我国农村草木炭资源十分丰富,一个5口之家,只要注意收存一年可积草木灰1000多公斤,相当于10O—120公斤氯化钾,可供5亩农田施用。但是,有些农户贮集草木灰方法不当,如将草木灰倒在房
With cropland multiple cropping index increasing year by year, potassium in soils is taken away by crops more and more. Soil potassium deficiency has become one of the most important obstacle factors for crop yield. However, at present, the supply of potash fertilizer is in short supply. In order to steadily improve the crop products and quality, it is very important to actively develop and rationally utilize the potash resources of farmers. 1, scientific storage of ash. Ash is an important farmhouse potash fertilizer, generally 5-8% potassium, 50 kg ash that is equivalent to 5-6 kg of potassium chloride. China’s rural grass charcoal is very rich in resources, a 5-family, as long as the note can be stored for one year more than 1,000 kg of grass ash, the equivalent of 10O-120 kg of potassium chloride for 5 acres of farmland application. However, some farmers collect ash improperly, such as putting ash in the room
