从探索调整田间小气候效应充分发挥气候生产力,来发挥水、肥、上、种密等因素的综合增产潜力而提高向日葵产量出发,1982年进行了不同栽培方式的试验。一、试验材料和处理(一)供试品种白葵杂1号。(二)处理方式共10种栽培方式,三次重复,30个试验小区。行距均为70厘米。清种方式株距65、55、45、35;2:1方式(两行向日葵一行苜蓿草),株距35、30、25;1:1方式(一行向日葵一行苜蓿草),株距30、25、20。小区面积200平方米。(三)管理播种时及现蕾前每埯各施硝酸铵5克。一对真叶展开时间苗、防虫害、缺苗座水补苗。(?)耥2-3遍。中间灌水三次。
From exploring and adjusting the microclimate effect in the field to give full play to the climate productivity, we should make full use of the yield potential of water, fertilizer, upper and seed density and other factors to improve the yield of sunflower. In 1982, different cultivation methods were tested. First, the test materials and processing (a) the test varieties white Kwai miscellaneous. (B) a total of 10 ways to deal with cultivation methods, three replicates, 30 pilot area. Row spacing is 70 cm. Qingbian way 65,55,45,35; 2: 1 way (two rows of sunflower alfalfa line), spacing 35,30,25; 1: 1 way (one line of sunflower alfalfa line), spacing 30,25,20 . Area of 200 square meters. (C) the management of sowing and budding each before each 5 grams of ammonium nitrate. A pair of real leaves to start time seedlings, pest control, seedlings seat water Miao. (?) 耥 2-3 times. Three times in the middle of irrigation.
