近几年来,河南棉花种植制度,正逐步由传统的一年一熟制向粮(油)棉间套,复种一年两熟制方向发展。为了正确估价不同种植制度的利弊,有必要对如何建立河南棉田合理耕作制度问题进行探讨。一、不同种植制度的经济效益首先从产值方面衡量。根据试验资料和现行价格估算,在中等肥力的水浇地条件下,一熟制棉花,亩产皮棉150斤左右,总产值约252.56元;麦套棉,一般每亩可收小麦300斤左右,亩产皮棉约减产一成,为135斤左右,总产值约277.56元;麦茬棉,每亩可
In recent years, Henan cotton planting system, is gradually from the traditional one-year system of grain (oil) cotton intercropping, double cropping system in one year of development. In order to properly evaluate the pros and cons of different cropping systems, it is necessary to discuss how to establish the rational farming system in Henan cotton field. First, the economic benefits of different planting systems are measured first in terms of output value. According to the test data and the current price estimates, under moderately fertile irrigated land, one-man-made cotton produces about 150 kg of lint per mu and the total output value is about 252.56 yuan. In wheat-paddy cotton, about 300 kg of wheat per mu is generally harvested, About 10% reduction in output of lint per mu, about 135 pounds, the total output value of about 277.56 yuan; wheat stubble cotton, per acre
