Nutrient solution for improving flower bud quality of jujube tree and preparation method thereof

Abstract

The invention provides a nutrient solution for improving the flower bud quality of a jujube tree and a preparation method thereof. The nutrient solution is prepared from the following raw materials in parts by weight: 300 to 450 parts of water, 75 to 85 parts of water-soluble coal-based ore source potassium (sodium) humate, 100 to 200 parts of compound amino acid, 100 to 150 parts of choline chloride, 50 to 100 parts of cycocel, 50 to 200 parts of potassium tripolyphosphate, 50 to 100 parts of potassium formate, 5 to 15 parts of borax, boracic acid or disodium octoborate tetrahydrate, 5 to 30 parts of EDTA complex trace elements, 3 to 5 parts of AES or AEO and 0.5 to 1.2 parts of xanthan gum. The product stability is high; the content of major elements is not lower than 320g / L; the microelement content is 2 to 10 g / L; the flower bud differentiation of the jujube tree can be improved; the inflorescence fullness is promoted; further, the fruit setting rate and the yield can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient solution for improving the quality of jujube flower buds and a preparation method thereof. Background technique [0002] In recent years, due to its natural environment and geographical advantages, Xinjiang has become the largest cultivation area for dried jujubes in China, and the quality of jujubes is extremely superior. However, due to the special climatic conditions and high-density cultivation mode in Xinjiang, Xinjiang jujube trees will soon enter the freezing solar term after being picked in November, and the use of confinement fertilizer and base fertilizer cannot be used, resulting in insufficient nutrition for the tree. Vigorous growth, fierce competition with flower bud differentiation for nutrients, root topdressing in spring due to low ground temperature, limited nutrient absorption, transformation, and transportation of roots, and poor mobility of P, ...

Problems solved by technology

However, due to Xinjiang's special climate conditions and high-density cultivation mode, Xinjiang jujube trees soon entered the freezing solar term after being picked in November, and the use of confinement fertilizer and base fertilizer was not possible, resulting in insufficient nutrition for the tree body. Vigorous growth, fierce competition with flower bud differentiation for nutrients, root topdressing in spring due to low ground temperature, limited nutrient absorption, transformation, and transport by roots, and poor mobility of P, B, Zn and other elements required for flower bud differentiation in saline-alkaline soil in Xinjiang , the utilization rate is low, and the effect is poor, resulting in low flower differentiation quality in the early stage, weak flowers, small flowers, and underdeveloped flower organs, which affect the fruit setting time and quality of jujube
