Abstract

The invention discloses a high-quality flower and fruit protection planting method for citruses under overcast and rainy low-temperature stress. By steps of pruning for strength accumulation, flowering promotion and flower protection, flower thinning and fruit protection, winter management and the like, the problem of flower bud differentiation interruption or nonuniformity in differentiation dueto weak organic matter synthesis action caused by less light in overcast and rainy days can be solved, problems that young fruit maldevelopment causes malformed fruits and fruits with diseases and pests and intensifies abnormal physiological flower and fruit falling and the like are solved, high-quality flower and fruit protection is realized, the flower bud abnormal differentiation rate is averagely decreased by 51.39%, and the year-by-year variation amplitude of the robust flower bud rate is not obvious. By adoption of the planting method, the citrus yield per mu in the third year is up to 3652.54kg per mu, the average increase rate in successive years reaches 10.40%, and planting effects are evidently higher than those of a control group.

Description

technical field [0001] This field belongs to the field of agricultural product planting technology, and specifically relates to a planting method for high-quality flower and fruit preservation of citrus under rainy and low temperature stress. Background technique [0002] my country is one of the important origins of citrus. It is rich in citrus resources and has a variety of fine varieties. It has a cultivation history of more than 4,000 years. After long-term cultivation and selection, citrus has become a precious fruit for human beings. Coupled with the fact that its value can be well realized during the planting process and it is environmentally friendly, citrus planting is increasingly favored by people. [0003] As we all know, plant flower and fruit drop is a widespread natural phenomenon that flowers, fruits, seeds, etc. are separated from the main body of the plant. During the normal growth and development of plants, in order to adapt to adversity stress (such as d...
