松滋县八宝公社12万亩耕地中,除8万亩棉田外,有水田1.25万亩,其中每年留晚稻苗田面积达3,000余亩。从充分利用土地出发,他们根据棉花早中期植株小,而杂交稻根系发达利于旱育的特点,在收过蚕豆的棉行中套播威优6号。于6月12日播种(播幅1.5尺,距棉0.5尺),7月18日移栽。此期间雨日6天,共灌水95.2毫米,除7月9日追施尿素用水5担外,未浇过水。结果,在1.05亩面积上获亩产水稻1,289斤,比同期播种插秧的0.69亩水秧增产7.7%;由于施底肥时间与棉花蕾肥同步,所以棉花也获亩产138.2斤,增产8.4%。 根据生育期间观察的和考种结果,分析棉套秧增产原因是:①秧苗矮壮,移栽时高仅26.3厘米,比水秧矮11.2厘米;栽后返青快、分蘖早,8月16日出现最高苗峰,比水秧早3
Songzi County Babao commune 120,000 acres of arable land, in addition to 80,000 acres of cotton fields, paddy fields 12,500 acres, of which each year to stay late rice seedlings area of 3,000 acres. Starting from making full use of land, based on the fact that early and mid-term cotton plants are small and hybrid rice roots are well developed and drought-tolerant, they are sown in the cotton line that received broad beans. Sown on June 12 (sowing 1.5 feet, 0.5 meters from cotton), July 18 transplanting. Rainy days during this period 6 days, a total of 95.2 millimeters of irrigation, with the exception of July 9, topdressing 5 tons of urea water, not poured over the water. As a result, 1,289 jin per mu of paddy rice was harvested on 1.05 mu of land, an increase of 7.7% over that of 0.69 mu of transplanted rice seedlings over the same period. Due to the maturity time of base fertilizer was synchronized with that of cotton buds, the yield of cotton was 138.2 jin, an 8.4% increase. According to the results observed during the fertility test and seed test results, cotton seedling yield analysis is: ① seedlings sturdy, transplanting height of only 26.3 cm, 11.2 cm shorter than watery seedlings; transplanted quickly after tillering, early tiller, August 16 appear The highest Miao Feng, 3 days earlier than the water seedlings
