我地复种指数高,季节矛盾突出,特别是多雨年份,往往烂耕烂种。若天气干旱,粗耕粗种,“三籽”(深籽、丛籽、露籽)严重,影响齐苗,抗旱催苗,又易致土壤板结,影响麦苗生长。这是我县三麦低产的原因之一。为了解决上述矛盾,我们于81、82两年,在南翔、望新等公社十多个点进行了稻板麦免耕试验,试验面积共15亩。处理有以下几种:1.免耕套种。在收稻前10～15天套播,收稻后,上肥
My multiple cropping index is high, the contradictions of the season are prominent, especially in rainy years, often rotten and rotted. If the weather is arid, rough farming crude species, “three seeds” (deep seeds, clump seed, exposed seeds) serious, affecting Qi Miao, drought seedlings, but also easy to cause soil compaction, affecting wheat seedling growth. This is one of the reasons for the low output of Sanmai County. In order to solve these contradictions, we conducted rice-free wheat-tillage trials in more than 10 sites in Nanxiang and Wangxin in 81 and 82 years, with a total area of 15 mu. There are several treatments: 1. No-tillage intercropping. 10-15 days before rice harvesting sets, after receiving rice, fertilizer
