The so-called cotton precocity, the definition of a first income as a percentage of total income; second refers to a specific period of time can reach a certain level of production or in the shortest time after sowing showed a good production potential. From the precocious cotton plant components, should be early flowering sooner or later, fruiting branches of the births and abdomen, camping organ and reproductive organs vertical and horizontal length of the birth interval, the growth period and so on. So how to achieve in different years to improve cotton precocity, cotton precocity and those factors are closely related to ways to improve cotton precocity and measures, where to start to solve the following to talk about a few crude ideas:
