辽葵杂2号是适应江苏沿海地区种植的油用向日葵品种,1986至1987年我站引种并对其栽培技术进行研究,获得亩产高达201.0公斤,经济收益较玉米间大豆每亩增加14.00元左右。现将其高产栽培技术分述如下: 1.适期播种纯种田为4月上旬,麦田套种为4月中旬。沿海地区具有明显的海洋性气候,春季气温回升慢,3月中、下旬气温3.3～9.1℃,平均为5.83℃,4月上旬气温明显回升,气温4.8～13.2℃,平均为9.77℃。在3月中、下旬播种,低温显著影响出苗,3月16日播种,27天后出苗,出苗率仅有
Liao Kui miscellaneous No. 2 is to adapt to the oil sunflower varieties planted in the coastal areas of Jiangsu, 1986-1987 I station introduction and its cultivation techniques to study, get up to 201.0 kilograms per mu, the economic benefits of corn than corn increased 14.00 yuan per mu about. Now its high-yielding cultivation techniques are described below: 1. Sowing purely suitable for early April planting, wheat interplanting in mid-April. The coastal region has a clear maritime climate. The spring temperature rebounded slowly. In the middle and late March, the temperature was 3.3-9.1 ℃ with an average of 5.33 ℃. The temperature rose sharply in early April and the temperature was 4.8-13.2 ℃ with an average of 9.77 ℃. In mid-March, late sowing, low temperature significantly affect the emergence, sowing on March 16, 27 days after emergence, the emergence rate of only
