近年我县春花生适当提早了种植期,获得了显著的增产效果,一般增产15—20％。很多地方春花生提早在立春至雨水播种,种植期较往年提早了一个月。我县花生高产区羊角区爱群乡1977年春花生760亩,由于提早种植,推广珍珠豆型品种粤油551,平均亩产434斤,比1976年亩增39.6％,其中高产片150亩,亩产627斤。大牙区华楼乡,1979年一块高产田在阴冷天气严重的年份,提早在2月17日种植,获得高产,亩产838.6斤。电白县农科所在1980年春季雾大、湿度高、阳光少的天气条件下,一块试验田提早在2月21日种植,获得亩产856斤。这些高产田的经验,给了笔者有益的启示,因此设置了早植增产效果的研究。
In recent years, my county spring peanut planting earlier appropriate, access to a significant yield increase, the general increase of 15-20%. Spring peanuts in many places early in the spring to rain sowing, planting earlier than in previous years for a month. In the county peanut high yielding claw area love group rural 760 acres of peanut spring 1977, due to the early planting, promotion of pearl bean varieties Yueyou 551, the average yield of 434 catties, 39.6% more than the 1976 acres, of which 150 acres of high-yield film, mu Producing 627 pounds. Large tooth area Huarou Township, 1979 A piece of high-yielding fields In severe weather in cold weather, early February 17 planting, access to high yield, yield 838.6 kg. Dianbai County Agricultural Department in the spring of 1980 foggy, high humidity, low sunshine weather conditions, a pilot field early in the February 21 planting, access to 856 kg per mu. The experience of these high-yield fields gave the author a useful inspiration, so set the effect of early planting yield study.
