Method for cultivating Zaozhong No.6 loquats

Abstract

The invention discloses a method for cultivating Zaozhong No.6 loquats, which belongs to the field of fruit tree cultivation. The purpose of the invention is to solve the technical problems that: under the climatic conditions of high atmospheric temperature in winter and spring, sufficient sunlight in the four seasons and large temperature difference between day and night, the total flowering rate of Zaozhong No.6 loquats is low, the early blossoming proportion is high, the fruit-setting rate is low, fruits are small and sour, and the fruits can hardly become commodities. The method includes the following steps: (a) pre-pruning; (b) cutting off the apical buds of early blossoming base shoots of Zaozhong No.6 loquats, and promoting resprouted shoots; moreover, choosing offshoots on the bases of spike-stalks to remain; cutting off all offshoots on spring shoots; and using the resprouted shoots and the offshoots on the bases of the spike-stalks as preliminary bearing base shoots; (c) cultivating the bearing base shoots; (d) stopping shooting, and promoting blossoming; (e) controlling pests at the flowering stage, and increasing the fruit-setting rate; (f) managing fruits. When the method is adopted, early blossoming is overcome, the total flowering rate is high, the yield is high, the quality of the fruits and the percentage of commercial fruits are sufficiently increased, and an unexpected effect is achieved.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a method for cultivating Zaozhong No. 6 loquat. Background technique [0002] Zaozhong No. 6 loquat was bred by crossing Jiefangzhong loquat as the female parent and Morio Zaosheng loquat as the male parent. The variety began to be tested in the second year of planting, with a plant yield of about 2 to 3 kilograms; it was fully put into production in the third year, with a plant yield of about 10 to 15 kilograms, and it was launched 15 to 20 days earlier than ordinary loquats. This variety has early maturity, high quality, large fruit, strong resistance, high and stable yield, strong market competitiveness and high economic benefits, and is favored by fruit farmers and consumers. [0003] The cultivation method of Zaozhong No. 6 loquat in the prior art is: [0004] 1. Colonization [0005] Loquats are most afraid of stagnant water and cause moldy roots. Deep d...

Problems solved by technology

[0030] Although the Zaozhong No. 6 loquats cultivated with the above-mentioned prior art methods in Fujian Province or other few areas have good quality and large fruit shape, when they are transplanted to areas with high temperature in winter and spring, sufficient sunlight in four seasons, and large temperature differences between day and night , such as Xichang, Panzhihua, and parts of Yunnan, the advantages of Zaozhong No. 6 loquats will no longer exist, and there are two main problems: one is that due to climate problems, the flowering and fruit-picking periods are delayed for a long time, and early The flowers are particularly serious, blooming successively from June to January of the following year, and the fruits are ripe from September to May of the following year; because the flowers blooming from June to September are basically unable to set fruit, and occasionally the fruit is small and difficult to sour. Form a commodity, so this batch of flowers is called early flowering, and the branches that bloom early flowering are called early flowering branches

The second is that the flowering rate of loquats after transplanting is low, about 60-70%, while the flowering rate of loquats in Fujian Province is about 80-90%.

The overall flowering rate is low, the proportion of early flowering is high, and the amount of flowering at the right time is seriously insufficient. As a result, in the case of high temperature in winter and spring, sufficient light in four seasons, and large temperature difference between day and night, the economical value of Zaozhong No. 6 loquat is still low. very low yield
