广州地区早春多阴雨、湿度大,时有寒潮入侵,常造成瓜类蔬菜出苗率和成苗率低、幼苗徒长、病虫害多等现象,给早春瓜类蔬菜生产造成了一定的影响。我所经过多年的研究实践,利用大棚穴盘育苗技术,集中大规模为农户培育优质壮苗,较好地解决了这一生产难题。现将该技术介绍如下:1基? In the early spring in Guangzhou, there are more rainy days, more humidity and sometimes cold water intrusion, which often result in the emergence rate and the seedling emergence rate of melon vegetables are low, the growth of seedlings is long, pests and diseases are numerous, and the melon vegetable production is affected to some extent. After many years of research and practice, I use large-scale cultivation of pot seedling technology, focusing on large-scale cultivation of high quality seedlings for farmers, a better solution to this production problem. The technology is introduced as follows: 1 base?
