Indeterminate-cultivation pruning method for hot pepper

The invention discloses an indeterminate-cultivation pruning method for hot pepper. Before hot peppers become dense, only the root of each pepper plant is subjected to soil moisture conservation and soil loosening, and water flush fertilizer is applied timely. After the dense peppers at the top of each pepper plant set normally, four main branches are selected, and other lateral branches are pinched or twisted. Later, more fertilizer is applied, and water is sprayed. After the dense peppers at the top of each pepper plant are ripe and harvested, the four main branches are hung with hanging cords, and all excess branches are removed. When the pepper plant continues to set fruits, fruits are reserved on the four main branches and lateral branches on the main branches. After fruit setting, the lateral branches are pinched. After the peppers on the main branches and the lateral branches of the main branches are ripe and harvested, the lateral branches are moved. The method is cycled to allow the main branches and the lateral branches to grow and set fruits indeterminately. By the pruning method, the plants are kept vigorous in early stage of growth of the peppers, fruit setting rate is increased, and early yield is increased. Light transmission in mid- and late stage of the peppers is increased, photosynthesis is enhanced, air permeability is improved, disease resistance of the hopper pepper is enhanced, and high yield and high quality in the whole grow cycle of the hot pepper are guaranteed.
