Cotton “Zhitong” is the use of plastic film directly covered in the cotton field cotton seedling nursery, no longer transplanted. This is the development of cotton seedling transplanting technology is a new cultivation technology. Currently used for seed breeding and small-scale high yield demonstration. The main advantages are: greatly early growth period; can significantly increase production; favorable yield bumper harvest. According to a preliminary understanding of practice, it is now straightforward to produce 250 kg of lint per mu yield structure, growth and important cultivation measures discussed as follows: Straight
