Embodiment 1

[0016] 1. Select a site to build a garden

[0017] Choose to build gardens on flat land away from cities, industrial and mining enterprises, villages, stations, docks, highways, etc., with good ventilation, good light transmission, deep soil, fertile soil, and convenient drainage and irrigation. The orchard of this embodiment is located in Hongsheng Fruit and Vegetable Complex, Anhai Town, Jinjiang City, Fujian Province, with a construction area of ​​150 mu. The orchard is located at 118°24′~118°43′ east longitude and 24°30′~24°54′ north latitude. It has a subtropical marine monsoon climate with an average annual temperature of 18.6°C and an annual rainfall of 911.7~1231 mm. The water system is a natural rainfall. The cultivation method of dwarf and dense planting is adopted, and the distance between plants and rows is 1.5 meters × 2 meters, which is convenient for field operation, keeps the orchard well ventilated, reduces the occurrence of diseases and insect pests, and is c...

Abstract

The invention discloses a no-pollution standardized high-yield method for cultivating guava, which comprises the steps of field selection, orchard establishment, pruning of guava plants, solid manure management, water management, pest control, and flower and fruit management, wherein in the plant pruning, the plant is pruned into a short-trunk multi-bough round head shape so as to culture a stunting crown; in the solid manure management, basic manure and supplementary fertilizer are combined, wherein the basic manure is applied by combining deep tillage after harvesting in spring, the supplementary organic fertilizer is applied in time after fruit setting, and trace elements are supplemented by spraying fertilizer on the foliage; in the water management, weeds are covered within the range of crown to preserve moisture, and the water-saving irrigation system combining spray irrigation and trickle irrigation is utilized; in the pest control, the comprehensive agricultural measures are utilized to cooperate with spraying of high-efficiency low-toxicity low-residual pesticide, orchard management in winter and spring is actively developed, and physical pesticide control technology is popularized; and in the flower and fruit management, flower thinning and fruit thinning are carried out according to the tree vigor and nutritional status, and the fruits in the whole orchard are filled in bags. The invention has the characteristics of low pesticide residue, high fruit quality and low environmental pollution.

Description

technical field [0001] The invention relates to a pollution-free standardized high-yield cultivation method of guava, which belongs to the technical field of agricultural cultivation. Background technique [0002] At present, food safety has become one of the hot issues of global concern. Pollution-free fruits not only require good quality, but also require low content of harmful substances such as pesticides and heavy metals, and have little adverse effects on human health. The implementation of pollution-free production of agricultural products is an effective method to meet the needs of consumers and improve the quality of agricultural products, and it is also an important means to deal with technical barriers to international trade and improve the comprehensive competitiveness of agricultural products. [0003] Guava ( Psidium guajava L. ) is a perennial evergreen woody plant and is an important tropical and subtropical fruit. Guava fruit is bright in color, tender ...
