Method for relieving white flesh loquat freeze injuries by means of flower property regulating technology

Abstract

The invention discloses a method for relieving white flesh loquat freeze injuries by means of the flower property regulating technology. The method comprises the following steps that 1, real-time environment change data of a garden and local meteorological data are combined and analyzed, and the regularity for freeze injury and low temperature happening time is found; 2, simulation of different degrees is performed on the drafted frozen injury grade and in-vitro tissue; 3, the leaf and soil nutrient consumption condition under the open-field condition is calculated, and the absorption time andspeed are determined; 4, according to the combined and analyzed air temperature data and freeze injury simulation result, on the basis of the actual schedule of plant nutrient consumption, the fertilizing time, number and variety are determined, and the plant flower property regulation operation is performed. According to the method, the plant flowering phase can be put off by 20-25 d or longer,and therefore freeze injuries can be effectively avoided or relieved. Compared with a traditional method, the freeze injury effective rate under the same condition can reach 100%, and the young fruitfrozen rate under the medium and heavy weather can be lowered by 80% or more.

Description

technical field [0001] The invention relates to the category of preventing freezing damage of Baisha loquat, in particular to a method for alleviating freezing damage of Baisha loquat by utilizing flower property regulation technology. Background technique [0002] Baisha loquat is a seasonal fruit with yellowish white skin and milky white flesh. The flesh is soft and crisp, juicy and high in sugar. The soluble solid content is 14%-16%. It is more than 4-5 times that of similar red sand varieties, and has good economic benefits. For this reason, in recent years, the development speed of Baisha loquat has been higher than that of Hongsha in all parts of the country. Whether it is a suitable area or a non-suitable area, this is mainly the result of growers being affected by price-driven factors and regardless of site conditions. [0003] However, since ancient times, there has been a saying that "loquats are delicious and difficult to grow". The most important reason is that ...

Problems solved by technology

In that way, since the average cost of facilities is as high as 16,000 yuan / mu per year, it is difficult to promote cultivation on the surface. Only demonstration sites and test areas subsidized by government departments can carry out small-scale cultivation.
