How to grow oranges to prevent drought? Please give guidance to citrus cultivation vulnerable to spring drought and summer drought. Spring drought mainly occurred from February to May, which was characterized by the influence of flower bud differentiation, low water and abnormal shedding of late-maturing citrus, curly leaves, increased abnormal flowers, granulation and water loss of fruit cysts, decreased quality, high temperature and drought in flowering period, and shortened flowering period. affect pollination and fertilization. Summer drought mainly occurs from July to September, where the frequency of summer drought is high on both sides of the Yangtze River, which is characterized by leaf withering and curling in severe cases; sunburn occurs in the fruit, when the pericarp is close to the pulp, or sunken and dry to form scar spots, juice cysts are withered, the pulp is granulated, and the taste is light. In this regard, the following simple and practical drought prevention and drought resistance techniques can be adopted in citrus cultivation: 1. Grass cultivation: keep grass or plant green manure crops such as legumes and clover between rows of orchards from March to June. Killing grass and covering before the dry season can not only reduce soil evaporation consumption, but also reduce soil and water loss. two。 Tree plate mulching: tree plate mulching with weeds, straw or cutting green manure can not only reduce temperature and moisture, but also increase soil organic matter, improve soil fertility, and is beneficial to the normal growth of fruit trees. The thickness of the cover is 10-20 cm, the gap between the mulch and the trunk is 10-15 cm, and a thin layer of soil is covered on the cover, the effect is better. 3. Hole irrigation to resist drought: when drought occurs, water sources and irrigation conditions are limited, dig a hole of 30 cubic meters at the dripping places on both sides of the crown, each irrigation 50kg / plant, cover the irrigation hole with grass, 7 days a cycle.
