在棉花生产过程中,如何利用与控制棉花“三发”(霉发、伏发和秋发),以争多座“三桃”(伏前挑、伏桃和秋桃),是夺取棉花高产的关键。棉花“三发”与外界环境条件之间关系很密切,而环境条件则又随着光温水等气象因子的变化而改变。温度的高低能使生育期提早或推迟,雨量的多寡,能造成棉株的徒长或滞缓。日照的多少影响光合作用及干物质的积累,从而影响着棉花的产量和品质。霉发——争发棵多座桃要获得棉花的高产,首先要求棉株有稳健的苗架,以促进发棵稳长,为多座伏桃创 In the cotton production process, how to use and control cotton “three” (mold hair, volts and autumn hair) to fight more than three “Peach” (volt pick, peach and autumn peach), is to seize the cotton yield key. Cotton “three” with the external environment is closely related to environmental conditions, environmental conditions and then with meteorological water and other meteorological factors change. The level of temperature can make the growth period earlier or delayed, the amount of rainfall, can cause the cotton plant leggy or stagnant. How much sunshine affects photosynthesis and dry matter accumulation, thus affecting the yield and quality of cotton. Moldy hair - to fight more than peach Peach to get high yield of cotton, first of all require cotton plants have a robust seedlings, in order to promote the growth of a stable tree, for more than V Peach Chong
