Method for cultivating big five-pointed star loquats on shady slopes

Abstract

The invention discloses a method for cultivating big five-pointed star loquats on shady slopes, 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 big five-pointed star 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) the big five-pointed star loquats cultivated on the shady slope are pre-pruned; (b) the method of irrigation and fertilization is utilized to promote early spring shoots to sprout new shoots within the period of time from late spring to early summer, and the shoots are called late-spring and early-summer shoots; offshoots on the bases of spike-stalks are chosen to remain; offshoots on the spring shoots are chosen to remain; and the late-spring and early-summer shoots, the offshoots on the bases of the spike-stalks and the offshoots on the spring shoots are used as preliminary bearing base shoots; (c) the bearing base shoots are cultivated; (d) shooting is stopped, and blossoming is promoted; (e) the fruit-setting rate is increased; (f) fruit management is carried out; (g) fruits are harvested. When the method is adopted, early blossoming is overcome, the total flowering rate is high, the yield is high, the quality of the fruits is high, 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 big five-star loquats on shady slopes. Background technique [0002] Dawuxing loquat is a new high-quality large-fruited loquat variety bred in Longquanyi District, Chengdu, Sichuan in 1978. It is named Dawuxing because of its large and deep five-star navel. Because of its high quality and large fruit shape, its market price is 1-2 times higher than other high-quality varieties, so it is also known as the king of loquats. [0003] The cultivation method of big five-star loquat in the prior art is: [0004] 1. Dig planting pits (holes): Before planting, dig planting pits (holes) in rows and at a plant spacing of 3×2m, with a width of 80-100cm and a depth of 60-80cm, and press in layers of organic fertilizers such as weeds, branches, and crop orange stalks. , 2000kg of weeds per mu, 200kg of phosphate fertilizer. The ridge is about 15cm ...

AI Technical Summary

Problems solved by technology

[0017] Although the big five-star loquats cultivated with the above-mentioned prior art method in Longquanyi District or other few areas are of high quality and full fruit shape, when it is transplanted to areas with high temperature in winter and spring, sufficient sunshine in four seasons, and large temperature difference between day and night, as In Xichang, Panzhihua, and parts of Yunnan, the advantages of the big five-star loquat no longer exist, and there are two problems: one is that due to climate problems, the flowering and fruit-picking periods are delayed for a long time, and early flowering is particularly serious. It blooms successively from June to January of the next year, and the fruits are ripe from September to May of the next year; because the flowers that bloom from June to September are basically unable to set fruit, and occasionally the fruit is small because of the fruit and fruit, and the taste is sour that it is difficult to form a commodity. This batch of flowers is called early flowers, and the branches that bloom early flowers are called early flower branches.

The second is that the flowering rate of loquats after transplanting is low, about 60-70%, while the flowering rate of loquats in Longquanyi District, Chengdu 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 sunlight in four seasons, and large temperature difference between day and night, the economic yield of the big five-star loquat is very low.
