Fruit-cracking preventing method for jun jujube cultivated in drought desert oasis in dwarf compact planting mode

Abstract

A fruit-cracking preventing method for jun jujube cultivated in a drought desert oasis in a dwarf compact planting mode comprises the following steps of jujube garden mesh coverage, (2) jujube garden ground surface coverage, and (3) leaf surface fertilizer supplementation in the fruit developmental phase. By means of the fruit-cracking preventing method, the changes of the temperature and the humidity of a jujube garden are effectively controlled, dew formation on the surfaces of the jun jujube fruits is avoided, the photosynthetically active radiation of the jujube garden in the hottest month is properly lowered, the photosynthesis of leaves is enhanced, it is promoted that the jujube flesh tissue is compactly developed, the fruit cracking degree of the jun jujube is relieved through control over the two aspects of the internal cause and the external cause, so that the occurrence of black spots and rot of the jujube fruits is reduced, the purpose of increasing the high-quality fruit rate is achieved, and great significance is achieved on the healthy and sustainable development of the red jujube industrial in Sinkiang.

Description

technical field [0001] The invention relates to a method for preventing fruit cracking of jujube, in particular to a method for preventing fruit cracking of jujube in arid desert oasis for dwarfing and densely planting cultivation of jujube. Background technique [0002] Xinjiang's unique geographical advantages and advantages in light and heat resources have created unparalleled jujube quality, making the jujube industry a dominant tree species for the development of Xinjiang's forestry and fruit industry and one of the pivotal economic pillar industries in southern Xinjiang. At present, the jujubes cultivated in Xinjiang are dominated by the two varieties of jujubes, jujubes and jujubes. Especially in recent years, in the direct seeding and densely planted jujube orchards, the jujube variety has a large fruit and high quality, and the quality of the dried dates is better. The development area increased rapidly. However, most of the jujube producing areas in southern Xinji...

Problems solved by technology

In the prior art, plastic film greenhouses are used to prevent sunburn. For example, CN201210037942.8 discloses a high-yield and anti-cracking fruit cultivation method for red dates, but the plastic film is only covered on rainy days, and the plastic film is only covered on the top and middle upper part of the greenhouse skeleton. , does not play a role in preventing sunburn

And prior art utilizes plastic film short-term covering or the technology of buttoning film after jujube cultivation to regulate temperature and humidity. Ensure that the rainwater infiltrates into the roots of fruit trees during short-term heavy rainfall, avoiding the rapid change of soil moisture caused by rain after drought, and promoting fruit cracking through absorption; it can also prevent the soil temperature from rising due to high temperature and long-term covering of plastic film. The demand of the root system for oxygen, it can be seen that the plastic film cannot be covered for a long time, and the invention is troublesome to operate
