麦棉套种方式,直接影响着粮棉产量。目前麦棉套种方式主要有三一式、四二式、五二式、六二式四种。哪种套种方式好呢?我们于1991年作了调查,结果是:三一式亩产小麦380公斤,比五二式和六二式分别增产12.7%和18.8%;产皮棉87.9公斤,比五二式和六二式分别增产17.8%和19.4.%。四二式套种亩产小麦355公斤,比五二式和六二式分别增产4.7%和10.3%;产皮棉76.1公斤,比五二式和六二式分别增产2%和3.5%。可见在目前的管理条件下,以三一式套种为最佳,四二
Wheat and cotton intercropping methods, a direct impact on grain yield. At present, there are three main types of cotton intercropping methods, four two, five two, six two four. What kind of intercropping method is good? We conducted a survey in 1991, the result is: Sany type 380 kg of wheat per mu, than the May 2 and June 2 were 12.7% and 18.8% increase respectively; lint cotton 87.9 kg, Two-and six-two formula respectively increased by 17.8% and 19.4%. Four or two inter-planted hectares of wheat produced 355 kilograms, an increase of 4.7% and 10.3% respectively over those of May-February and June-February. 76.1 kilograms of lint was produced, representing an increase of 2% and 3.5% respectively over May-February and June-February. Visible under the current management conditions, to Trinity-type intercropping for the best, four two
