湖州市地处太湖南岸,气候温和湿润,年无霜期233～246天≥10℃活动积温5000℃左右,热量条件属三熟不足、二熟有余地区.过去冬作以大麦为主,近年来小麦播种面积逐年扩大.由于晚稻的收获期正是小麦的最佳播种期,使本来就非常紧张的季节矛盾更加突出.如遇不良天气条件的影响,往往造成小麦迟播,导致冬发苗不足,成穗率低下,不能稳产高产.晚稻行间套播冬小麦(简称套播麦,下同)的栽培技术,既能确保晚稻养老稻夺高产,解决发展迟熟高产晚粳稻的后顾之忧,又能使小麦适期早播夺高产,达到稻麦双丰收的目的.1998年全区推广套播麦8547亩,在大灾之年常规稻板麦严重减产的情况下,套插麦仍取得了平均亩产211.68kg的较好收成,比对照每亩增收15.68kg,增产8.2%,深受农户青睐.现将该栽培技术简介如下.
Huzhou City is located in the southern coast of Taihu Lake, mild climate, the annual frost-free period of 233 to 246 days ≥ 10 ℃ active accumulated temperature of about 5000 ℃, the heat conditions are three shortages, more than two areas. Past winter as barley, sowing in recent years The area is expanding year by year.As the harvest of late rice is the best sowing period of wheat, the already very tense seasonal contradictions become more prominent.In case of adverse weather conditions, often resulting in late-sowing of wheat, leading to winter hair shortage, into Spike rate is low, can not be stable and high yield. Late rice intercropping sowing winter wheat (referred to as sowing wheat, the same below) cultivation techniques, both to ensure that late rice plowing high yield, to solve late-growing high yield late japonica rice worries, but also make wheat The appropriate period of early broadcast wins high yield, to achieve the purpose of rice and wheat double harvest.In 1998 the whole area to promote sets of wheat sowing 8547 acres of rice, in the disaster of conventional annual rice crop serious case of cuttings, inserted cuttlefish still achieved the average yield per mu 211.68kg better harvest, than the control income 15.68kg per mu, yield 8.2%, favored by farmers. Now the cultivation techniques are as follows.
