Anti-freezing cultivation management method suitable for loquat orchard at mountainous area

Abstract

The invention belongs to the technical field of cultivation of grapes, fruit trees or similar trees, and discloses an anti-freezing cultivation management method suitable for a loquat orchard at a mountainous area. Anti-freezing facilities of the loquat trees cultivated in a sloping field is considered to be built in a physical mode. The key points of the facilities are as follows that materials such as a light-transmitting heat preservation film, a steel wire or a light alloy are made into a "canopy" type anti-freezing device, and promotion and application are facilitated. The anti-freezing cultivation management method suitable for a loquat orchard at a mountainous area comprises the following steps: selecting a planting area and selecting a cold-resistant excellent variety; carrying outfield growth management: planting 42 plants per mu, reinforcing fertilizer and water management, and shaping and trimming crowns, wherein the tree height is 2.5 meters or below; installing a "canopy"type anti-freezing outer cover for each single plant; and storing the device, carrying out topdressing on loquat tree bodies, carrying out moistening by spring rain, and finishing fruit thinning andbagging. The method provided by the invention can be used to better solve the technical problem that freezing prevention is difficult to achieve in existing loquat planting and production technologies. The device can be repeatedly used, so that cost investment of fruit farmers is greatly reduced, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of cultivation of grapes, fruit trees or similar trees, and in particular relates to an antifreeze cultivation management method suitable for mountain loquat orchards. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: loquats bloom and bear fruit in autumn and winter, and winter frost damage is one of the main natural disasters that cause loquat production reduction or even crop failure. Frost is a sharp drop in temperature in winter, and then a sharp rise in temperature. Water vapor condenses into frost, which freezes the tender parts of plant organs, and the greater the temperature change, the more serious the damage. The hilly mountains and low-heat valleys in southern my country are often the hardest hit by frost. . Therefore, it is very important to develop loquat flower and fruit antifreeze cultivation management techniques to ensure the sust...

Problems solved by technology

[0004] In the prior art, methods such as wind barriers, whitewashing, weeding, mulching, and tree crown spraying antifreeze agents are cumbersome, and the crown spraying antifreeze agents are easy to remain, requiring a lot of manpower and material resources, and the device cannot be reused, resulting in increased economic costs. question;

[0005] In the existing technology, methods such as heating, blowing, fumigation, and artificial rainfall are often used to resist cold, but there are problems such as high cost, difficulty in control, and environmental pollution. At the same time, the operability of the existing technology is not strong, the effect is poor, and it is not conducive to promotion
