Disease prevention planting method of dragon fruits

Abstract

The invention discloses a disease prevention planting method of dragon fruits, and relates to the technical field of planting. According to the method, sesames are planted in a large field in the previous year before fixed-planting of dragon fruits, after the sesames are harvested, the sesame straw is crushed, and uniformly mixed with 8-12% of bacillus, 20-30% of chitosan and 200-300% of humus soil in terms of the weight of the sesame straw, and then the mixture is evenly scattered into the large field, then the large field is covered with a layer of straw, and finally, a layer of urea is uniformly scattered on the straw, and the field is covered with a thin film; in the spring in the second year, the dragon fruits are planted by a column type cultivation method, purple perilla is plantedbetween the dragon fruit rows, and after the purple perilla is harvested, fennel is planted between the dragon fruit rows in the spring in the third year, after the fennel is harvested, the purple perilla is continuously planted, and the purple perilla and the fennel are circularly planted according to the method. According to the invention, the dragon fruits, the purple perilla and the fennel arereasonably interplanted and rotated, so that the occurrence of diseases and insect pests of dragon fruits is reduced, the purpose of pollution-free planting is achieved, and the yield is also improved.

Description

【Technical field】 [0001] The invention relates to the technical field of planting, in particular to a disease-preventive planting method of dragon fruit. 【Background technique】 [0002] Pitaya is a plant of the genus Trigonum in the cactus family. It is native to Central America and is currently planted in Hainan, Guangxi, Guangdong, Fujian and other places in my country. Dragon fruit is an emerging tropical and subtropical fruit tree, rich in nutrition, unique in function, containing a large number of medicinal ingredients, with high economic value, and its demand is increasing day by day. When dragon fruit was introduced in a small amount, there were few pests and diseases. With the increase of market demand, the planting area of ​​dragon fruit continued to expand, and the pests and diseases tended to increase, but the control technology was not yet mature. At present, the main diseases of dragon fruit are stem rot, base rot, anthracnose, fusarium wilt, black spot, stem b...

Problems solved by technology

At present, the main diseases of dragon fruit are stem rot, base rot, anthracnose, fusarium wilt, black spot, stem blight, canker and viral diseases; the main pests are wax mealybug, black thorn whitefly and moths etc.; these pests and diseases can harm dragon fruit fruits and plants, causing serious losses to dragon fruit losses. However, at present, the control of pitaya diseases and insect pests is mainly based on chemical pesticide control, which not only pollutes the environment, fails to achieve the effect of pollution-free planting, but also Extensive abuse of pesticides, pests and diseases tend to aggravate
