大麦田复种早稻,引起土壤理化性状改善,插后又处于较优越的温光条件下,使返青时间缩短,具有高产优势。但是大麦田复种早稻,插秧季节推迟,本田生育期缩短,对高产有一定的影响。通过三年的摸索,在栽培技术上应采取争穗,争粒、争粒重三并重的主攻路线。连作晚稻,前期温光充足,后期受寒露风威胁。因而栽培技术上要采取稳中求高的原则。实践表明。早稻采取三并重,晚稻采取稳中求高的技术措施,可使早稻亩产达500公斤以上。晚稻达450公斤以上。其技术要点是:
Barley multiple cropping early rice, causing physical and chemical properties of soil improvement, after plugging in the more superior temperature and light conditions, the green turning time shortened, with high yield advantage. However, multiple cropping of barley early rice, planting season postponed, shortening the growth period of Honda, have a certain impact on high yield. After three years of exploration, cultivation techniques should take the main line of fighting for grain, forging grain, and forging equal emphasis on grain. Even for late rice, early warm enough, the latter by the threat of cold winds. Therefore, cultivation techniques should adopt the principle of keeping one’s pace and keeping progressing. practice shows that. Early rice to take all three, late rice to seek stability in the technical measures to make early rice per mu up to 500 kilograms. Late rice up to 450 kg. The technical points are:
