一、目的和基本情况一个地区的蔬菜供应能否达到自给,大白菜产量高低往往占有举足轻重的地位。育苗移栽试验目的,就是为着解决稳产高产问题而提供科学依据。我区适宜大白菜生长季节很短,常规栽培方法只能利用70—80天的早熟品种。丰年平均单产在4,OOO斤左右徘徊,迂有灾年产量更低。八三年全区平均单产只有2,900多斤。为提高大白菜产量,拟对育苗移栽技术进行研究。二、供试材料及试验方法 1.供试品种:
First, the purpose and basic situation Whether the supply of vegetables in a region can achieve self-sufficiency, the level of Chinese cabbage often occupies a decisive position. Seedling transplanting test purpose, is to solve the problem of stable yield and provide scientific basis. My area suitable for a very short season of Chinese cabbage growth, conventional cultivation methods can only use 70-80 days of early maturing varieties. Annual average yield in hurried around 4,000 kg, less annual output of disaster-hit. In 1993, the average yield in the entire district was only 2,900 kilos. In order to improve the yield of Chinese cabbage, we plan to study the seedling transplanting technology. Second, the test materials and test methods 1. Test varieties:
