许多地方反映,早稻燥田割稻对晚稻生长的不良影响,主要是由于土块粗大僵实以及晚稻施肥水平低这两个因素引起的。关于土块大小问题的影响已进行了初步研究。但在晚稻高肥条件下,早稻燥田割稻对晚稻生长的影响如何,缺乏试验。为此,我们于去年进行了这方面的工作。试验是在本所试验场进行,试验田的土壤肥力和晚稻施肥水平都比较高。试验处理分为早稻燥田割稻和烂田割稻(对照)两种。方法:燥田割稻的从早稻分蘖后期搁田到收割为止, In many places, the adverse effects of early rice dry-land rice on late rice growth were mainly due to the two factors, that is, the large and stiff soil block and the low fertilization level of late rice. The impact of clods size has been studied tentatively. However, under the conditions of late rice and high fertilizer, the effect of early rice dry land cutting rice on late rice growth, lack of test. For this reason, we carried out this work last year. The test was carried out in our test site, and the soil fertility and late rice fertilization rates in the experimental field were relatively high. The experiment was divided into two types: early rice dry land cutting rice and bad land cutting rice (control). Method: Dry field cut rice from the early tillering of early rice Tiantian to harvest so far,
