冬油菜是我区东南部的主要油料作物,越冬保苗在我区是影响冬油菜高产、稳产的主要问题。现根据试验生产资料,对冬油菜安全越冬保苗的几项技术措施介绍如下: 一、精细整地,施足底肥。冬油菜前茬一般是冬小麦,种植冬油菜的地块,麦收后要早耕、深耕,有利接纳降雨和熟化土壤。八月上旬耙耱保墒,每亩施农家肥料4000～5000公斤,尿素10公斤,普通过磷酸钙25公斤以上,作基肥。浅耕翻肥,随耕随耱,使地面平整、细绵,
Winter rapeseed is the main oilseed crop in the southeastern part of our region. Overwintering seedling preservation in our district is the main problem that affects the high yield and stable yield of winter rapeseed. Are based on experimental production data, winter oilseed rape over the seedlings of several technical measures are described below: First, the fine preparation of soil, Shi foot fertilizer. Winter rapeseed crop is generally winter wheat, planting winter rapeseed plots, the wheat harvest after the early tillage, deep plowing, favorable to receive rainfall and maturity of the soil. In early August rake 耱 soil moisture, farm fertilizer per acre 4000 to 5000 kg, 10 kg of urea, common over 25 kg of calcium phosphate, as a base fertilizer. Tilling plowing, with farming plover, so that the ground is smooth, thin cotton,
