A kind of cultivation method based on improving raspberry fruit quality

Abstract

The invention provides a cultivation method based on improving raspberry fruit quality, which relates to the technical field of crop cultivation. The cultivation method comprises the following steps: (1) field selection; (2) variety and seedling selection; (3) soil improvement; (4) Set up rain shelter; (5) Set up cotton sunshade mesh; (6) Set up three-layer growth frame; (7) Ridging, drip irrigation and drainage; (8) Colonization; (9) Soil, fertilizer and water management; (10) Plastic pruning; (11) Cold protection and storage. The method of the present invention overcomes the problems of sunburn caused by too strong peripheral light in the conventional planting process of raspberries, perishable fruits in rainy seasons, poor fruit coloring caused by closed inner chamber light, dead seedlings caused by poor drainage in the garden, and unscientific fertilization caused by unreasonable fertilization. Decreased taste and so on. The cultivation method of the invention has high raspberry yield, large single fruit, excellent appearance quality, increased sweetness, strong flavor, increased price and significantly increased economic benefits.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method based on improving the quality of raspberry fruit. Background technique [0002] Raspberry (Rubus corchorifolius L.f.), erect shrub, 1-3 meters high. my country's Gansu, Tibet, Northeast China, Qinghai, Xinjiang and other places are widely distributed. Because raspberry has the effects of astringent, kidney-improving, yang-brightening, sobering up and quenching thirst, resolving phlegm and detoxification, the area of ​​artificial introduction and cultivation in the southern temperate zone and northern subtropical zone of my country is expanding year by year. [0003] However, the growth performance of most of the introduced and cultivated raspberries is relatively poor. The main reasons are as follows: [0004] One is that it is difficult for raspberries to spend summer. Raspberries are suitable for growing in temperate regions. Because of their ...

AI Technical Summary

Problems solved by technology

At present, the raspberries introduced and cultivated in the south are cultivated in the open field, and the shading effect is not obvious. Due to high temperature and high light intensity, their growth and development can easily cause growth obstacles.

[0005] Second, rainfall has a greater impact on fruit quality

Most of the raspberry planting areas do not adopt rain shelter facilities. However, the raspberry fruit period is from April to June, which coincides with the "plum rain season"; the raspberry fruit is exposed, and the rain washes and erodes the fruit color. Poor, perishable, short shelf life, significantly reduced commodity

[0006] Third, there is no stable growth posture

The side branches of raspberry are "vine-shaped", and the raspberry is a side branch that bears fruit. Under the action of the weight of the fruit, the whole tree of raspberry is very easy to grow randomly, which brings difficulty in pruning, closed tree body, decreased photosynthetic force of leaves, and congratulations in the lower part. The branches and leaves in the inner chamber are easy to die, causing the yield and quality to decline

[0007] Fourth, the drainage of the park is not timely or scientific

[0008] Fifth, the use of organic fertilizers is unscientific

The content of organic fertilizer in the soil of some raspberry gardens is insufficient, and the sugar content and taste of the fruit are reduced due to insufficient "carbon source" and other reasons; in addition, the one-sided application of chemical fertilizers leads to weakening of tree vigor and decline in resistance
