A tree body management method for improving mango fruit uniformity

Abstract

The invention relates to a tree body management method for improving the uniformity of mango fruits. The method comprises the following steps: after fruits are picked for 20 to 30 days, heavily pruning, burying and applying biological organic fertilizer, nitrogen-phosphorus-potassium compound fertilizer, calcium magnesium phosphate fertilizer, magnesium sulfate and chlorpyrifos granules, and irrigating water for each plant every 15 to 20 days; after the pruning is performed for 20 to 30 days, picking buds, applying trace element foliar fertilizer for two times; after the buds are picked for 35 to 45 days, controlling the water, and spraying and applying paclobutrazol, Silwet L-77, water-soluble fertilizer containing amino acid, tebuconazole, avi spirodiclofen suspension and boron fertilizer; after inflorescences are developed, pruning away inconsistent inflorescences; at a full-bloom stage, spraying and applying gibberellic acid, water-soluble fertilizer containing amino acid and pollinating and fruiting essence; after second-time physiological fruit drop, pruning away the inconsistent fruits, spraying and applying zinc thiazole, hexaconazole kresoxim-methyl, thiamethoxam-high chlorine-fluorine suspending agent and Shimahong foliage fertilizer, and bagging; when the maturity of fruits reaches 60 to 70 percent, pruning away shading blades of the fruits; picking up when the maturity of the fruits reaches 70 percent to 80 percent, thus obtaining high-quality mango fruits with the characteristics of uniform size and color at a mature stage.

Description

technical field [0001] The invention belongs to the technical field of tree body management of agricultural and forestry economic crops, and in particular relates to a tree body management method for improving the uniformity of mango fruit. Background technique [0002] Mango (Mangifera indica L.) is one of the important tropical and subtropical fruits. It belongs to the Anacardiaceae (Anacardiaceae) tall tree of the genus Mangifera. It has been cultivated for more than 4,000 years and is one of the oldest fruit trees in the world. Mangoes are cultivated in more than 100 countries in the world, spanning between 30 degrees north and south latitude, mainly distributed in Southeast Asian countries and regions such as India, Indonesia, Malay Peninsula, Thailand, etc., because of their wide distribution, beautiful fruit shape, sweet taste, and nutrition Rich, known as the "king of tropical fruits". At present, more than 1,000 mango varieties have been selected and bred at home a...

Problems solved by technology

[0003] Because the mango flower bud differentiation period and fruit development period are both long, the fruiting branches are not consistent with the aging period, resulting in the key links in the fruit development and ripening process are easily affected by the external environment, the same variety or even the same tree in the same orchard There are large differences in the period of flowering, fruit setting and fruit maturity, fruit shape, size, and fruit color. On the one hand, the fruit harvest cycle is longer, and the fruit of the same tree needs to be harvested in multiple rounds, resulting in increased labor costs. On the other hand, due to The inconsistency of fruit size and color leads to the need for artificial sorting when picking fruits before they are convenient for sale, storage and transportation. The inconsistency of fruit maturity, size and color has greatly affected the benefits of mango plantations and has caused serious damage to the development of the industry. Negative Effects

However, there are no relevant reports on how to effectively improve the tree management technology of mango fruit maturity, size and color uniformity at the same time, so the tree management technology to improve the uniformity of mango fruit remains to be developed
