The invention belongs to the field of planting technology, and specifically relates to a pruning method for adult late-maturing mango fruit, which is implemented as follows: during mid-September to mid-December, fruit is not pruned after harvesting to make it grow naturally; during late December to late February, trees are protected and cultured, plants are sprayed with 1000 times of high-efficiency Cyhalothrin solution, trunks are dried with quicklime water; and in early March to early April, trees are dried with 1,000 times of high-efficiency Cyhalothrin solution. In late May, the ineffective branches containing overdense branches, direct branches and overlapping branches in the crown were first pruned, and the inflorescences of the fruiting branches of the previous year were secondly pruned, and the spring shoots germinated on the fruiting branches of the previous year were retained 1 2. The rest were all pruned to ensure that the fruiting branches and nutrient branches of the current year were 2:1. In early May and late June, the fruiting branches were pruned first, and 1 2 fruits were retained in each inflorescence, and the rest were complete. Next, the shoots germinated on the last year's fruiting branches should be sparsely pruned and kept 1 2. With this method, the fruit bearing rate of mango plant can be maintained at about 65, and the yield and crown growth can be increased year by year.

技术介绍
杧果属漆树科(Anacardiaceae)杧果属(Mangifera)常绿热带果树,是世界五大名果之一,又名檬果、济果、闷果、蜜望等,起源于亚洲南部的印度以及东南亚的缅甸、泰国、马来半岛、印度尼西亚群岛和菲律宾等国家与地区,因其营养丰富和独特的风味,被誉为热带果王。印度是最早栽培杧果的国家,距今已有4000多年历史,经过长期发展演化和人工栽培,其分布范围已扩展至北纬28°~30°的热带亚热带国家和地区。我国的杧果主要分布在海南、广西、云南、广东、四川、福建和台湾,近年来,贵州省的部分地区也开始种植杧果,成为中国杧果的新兴产区。云南栽培杧果的范围较广,全省17个地、市、州中有16个地州市有杧果分布。从水平分布看,东部文山至西南的德宏(97°51′~105°38′E)、滇东北的巧家至最南边的西双版纳(21°29′~26°53′N)都有杧果分布;从垂直分布看,海拔30~1700m的广阔热带南亚热带地区都有栽培的杧果。常规成年杧果修剪方法,主要是在杧果采收后,树冠上部抽发的直生枝条应重剪,以控制株高和增强树体透光性;对树冠表层要轻剪,保证结果枝数量,对内膛枝要重剪,保证树体通风。而海拔在1200m以上,年均温17.5~20℃,年降雨量850-1500mm,≧10℃活动积温6000℃以上,冬季无霜或轻霜。在该区域内杧果普遍9月后成熟,因成熟较晚,气温开始下降,枝梢不易萌发,易形成枝条连续多年结果,造成生长量及产量逐年下降,抗逆性逐年降低,严重影响了果农的经济收入。若采 ...
【技术保护点】
1.一种成年晚熟杧果的修剪方法,其特征在于:1) 秋放:在9月中旬‑12月中旬期间,果实采收后不进行修剪,使其自然生长;2) 冬养:在12下旬‑2月下旬期间,保护及养树,用高效氯氟氰菊酯1000倍液喷施植株,树干用生石灰水涂干;3) 春剪:在3月上旬‑4月下旬,首先剪除树冠中包含过密枝、直生枝及重叠枝的无效枝条,其次剪除上年结果枝上花序,保留上年结果枝上萌发的春梢1‑2个,其余全部剪除,保证当年结果枝条和营养枝条2:1;4) 夏疏:在5月上旬‑6月下旬,首先疏剪结果枝上果实,每一花序保留1‑2个果,其余全部剪除;其次注意疏剪上年结果枝上萌发的梢保留1‑2个。
