1.适期播种,培育壮苗播种床应选择光照、排灌良好、土质肥沃的地块。苗床土不仅要具备各种矿质营养和丰富的有机质,而且还要有良好的物理结构。可用菜园土和充分腐熟的厩肥6:4配制而成,每10平方米再加过磷酸钙1公斤,尿素0.5公斤,大粪或鸡粪10公斤,充分拌匀、捣细、过筛。播种期根据不同地区和双亲特性而不同,陕西关中地区一般于9月下旬播种。如果播期晚了,越冬时植株太小,容易冻死。相反,播种早了,发育太快,同样不耐低温而造成越冬困难。播种方法有撒播和点播两种方法。点播较撒播有用种量少,出苗整齐,营养面积大,不易徒长等优点,应用较普
1. Appropriate seeding, nurturing seedling planting bed should choose light, irrigation and drainage well, fertile land mass. Bed soil not only have to have a variety of mineral nutrition and rich organic matter, but also have a good physical structure. Available garden soil and fully matured manure 6: 4 preparation, plus every 10 square meters superphosphate 1 kg, 0.5 kg of urea, manure or chicken manure 10 kg, mix well, pound thin, sift. The sowing period varies according to the characteristics of different regions and parents, and the Guanzhong region of Shaanxi is usually sown in late September. If the sowing date is late, when the winter is too small plants, easy to freeze to death. On the contrary, sown early, too fast, the same cold temperature caused by overwintering. Sowing methods are broadcast and on-demand two methods. Sowing more than sowing a useful species less germination tidy, large nutritional area, not easy to leggy and so on, the application is more general
