河北省南部农民根据当地光、热、水资源充足的条件,近年来摸索出了一条早春油葵——越夏菠菜——秋大白菜一年三种三收的高效种植模式,可亩收油葵250-300公斤,菠菜1500-2000公斤,大白菜4000-5000公斤。现将该种植模式种植技术介绍如下:一、油葵1、选用优良品种:选用高产、稳产、高效的油葵品种,可选用矮大头567DW、矮早丰等杂交品种。2、整地施肥:油葵根系较大,对养分吸收较多,为争取高产,必须加大底肥的投入,一般亩施有机肥2000-3000公斤,尿素10-15公斤,磷酸二铵20-30公斤,磷酸钾20公斤,耕翻深度在25厘米左右,以保证油葵生长快、长势强,同时增强其抗倒性。
According to local conditions of light, heat and water resources, farmers in the southern part of Hebei Province have worked out an early spring oil sunflower - summer summer spinach - autumn cabbage three kinds of three harvesting efficient planting mode, can be mu income Kwai 250-300 kg, spinach 1500-2000 kg, cabbage 4000-5000 kg. Now the planting mode planting techniques are as follows: First, the sunflower 1, the selection of fine varieties: selection of high yield, stable yield, efficient varieties of oil sunflower, can choose short head 567DW, short early Feng and other hybrid varieties. 2, land preparation and fertilization: oil sunflower root larger, more nutrient absorption, in order to strive for high yield, we must increase investment in base fertilizer, general Mushi organic fertilizer 2000-3000 kg, urea 10-15 kg, diammonium phosphate 20-30 Kg, potassium phosphate 20 kg, plowing depth of about 25 cm, in order to ensure fast growth of oil sunflower, growing strong, while enhancing its lodging resistance.
