Application of atomizing system to stress-resistant cultivation of loquats

Abstract

The invention provides an application of an atomizing system to stress-resistant cultivation of loquats and relates to the field of agricultural planting. By using the atomizing system, the fruit setting rate of each fruit cluster of white-flesh loquats easy to freeze can reach 7-8 averagely in a normal year and can reach 2-3 averagely in an extremely cold year so as to basically ensure that the yield of the white-flesh loquats is not affected by freezing damage, and the freezing damage loss is reduced by 20-40% and the yield is increased by 30% or above as comparison with those in a white-flesh loquat garden in which the technology is not applied; and in a mature period in summer, fruits in the loquat garden have the sun scorching rate of smaller than 10% and the commodity rate of 80% orabove, the sun scorching rate and the commodity fruit rate reach and are even superior to a bagging effect, while a garden in which atomization is not used achieves the sun scorching rate of 30-40% under a severe sun scorching condition and the commodity fruit rate of lower than 50%. By using the atomizing system in the loquat garden, the freezing damage and sun scorching of the loquats can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to the application of a mist system in the stress-resistant cultivation of loquats. Background technique [0002] Loquats are divided into Hongsha (yellow flesh) and Baisha (white flesh) varieties according to the color of the flesh. The white sand variety is more and more popular among consumers because of its tender meat, sweet taste like honey, and strong flavor. The price is much higher than that of the red sand variety. At present, the market price of Zhejiang Baisha loquat variety is 40-80 yuan / kg, much higher than the 16-20 yuan / kg of Hongsha variety. However, compared with Hongsha loquat, Baisha loquat is more susceptible to freezing during the flowering stage and young fruit stage, and sun-burned fruit at the mature stage, and its poor stress resistance leads to higher cultivation costs. In case of bad weather, the yield of Baisha loquat was seriously dama...

Problems solved by technology

[0003] In addition, Baisha loquat has fine flesh and thin skin. During the ripening period, the surface of the fruit is susceptible to sunburn caused by strong light, resulting in dark brown irregular depressions on the fruit.

Sunburn fruit is perishable and loses its commerciality in rainy and wet weather, resulting in reduced production and income

At present, the use of greenhouse facilities with external sunshade is an effective measure to prevent Baisha loquat from freezing in winter and sunburn at maturity. However, there are still many constraints in the application of these traditional facility cultivation: (1) The terrain is limited and can only be used on flat land. The Baisha loquat cultivation area is mainly in the mountainous area; (2) the investment is huge, 70,000 to 80,000 yuan per mu, which not all fruit farmers can bear; (3) the temperature and humidity management is complicated, and it is necessary to open and close the shed every day, which is time-consuming and laborious. Small-scale cultivation is not cost-effective
