Problems solved by technology

Most of the calcium in the tree is weakly acidic calcium salt, which exists in a solid or colloidal state. It is difficult for this calcium to be transferred to the fruit and to be fully utilized.
[0007] At present, there are many foliar calcium supplement products at home and abroad, from water-soluble calcium to organic chelated calcium, to organic compound calcium, and to bio-organic calcium. From the perspective of the development process, these calcium supplement products directly act on the leaves, but calcium It cannot be well run and absorbed by plants, and cannot fundamentally solve calcium deficiency diseases

Embodiment 1

[0017] Embodiment 1: a kind of calcium fertilizer, it by solid weight percent, calcium nitrate is 88.8%, amino acid calcium 10%, DA-6 is 1% and wetting agent is commercially available washing powder 0.2%, mixes and grinds finely to make , Dilute the solution 500 times with water when using it, spray about 300kg of water per mu, and spray three times after the apples fade and before bagging, with an interval of 10 days between each time.

[0018] This test is divided into three groups altogether, the first group is clear water control group; And the wetting agent is 0.2% of commercially available washing powder; the area of ​​the three groups is 3 mu, one test unit per mu, and three repetitions are set for each group. Dwarf red Fuji over 15 years old. Experimental data The first group of clear water control group has an average yield of 6560 catties per mu, the yield of first-grade fruit is 2013 catties (accounting for 30.6%), and the incidence of bitter pit disease is 31.3%; ...

Embodiment 2

[0019] Embodiment 2: a kind of calcium fertilizer, by solid weight percentage, calcium chloride is 40%, calcium nitrate 30%, amino acid calcium 10%, EDTA chelated calcium 10%, fulvic acid calcium is 8.7%, diethyl ethyl hexanoate 0.2% and diethyl hexanoate sodium salt 0.6%, wetting agent washing powder 0.5%, diluted 400 times with water when used, for the prevention and treatment of Chinese cabbage dry heartburn. The tested variety is Jiaozhou cabbage, each plot is 50 square meters, repeated 3 times, and clear water is used as control. Spray in the early stage of balling (that is, two weeks before wrapping the heart), once a week, and spray 3 times in total. The results show that the incidence of dry heartburn in the clean water control group is 22%, while the incidence of dry heartburn in the test group is only 4%. Production increased by 11.5%.

Embodiment 3

[0020] Embodiment 3: a kind of calcium fertilizer, by solid weight percent, EDTA chelated calcium is 99.4%, DA-6 is 0.4%, and wetting agent is washing powder 0.2%, dilute 500 times of liquid with water during use, foliar spray It is used for the prevention and treatment of tomato umbilical rot.

[0021] The tested variety was T powder 86 tomato, each plot was 50 square meters, repeated 3 times, and clear water was used as control. Spray at the young fruit-green fruit stage (starting two weeks after the young fruit is formed), and spray 3 times a week in total. The results show that the incidence of umbilical rot in the clean water control group is 12%, while the incidence of umbilical rot in the test group is only 4%. %, and increased production by 12.5%.

Abstract

The invention discloses a calcium fertilizer and an application thereof. The calcium fertilizer contains water-soluble calcium salt and a plant-growth regulating agent substance. The plant-growth regulating agent substance is amine hexanoate or salts thereof. Regional trials show that, when the calcium fertilizer is sprayed on leaves, the occurrence rate of apple bitter pox disease can be reduced from 27% to below 7%. Compared with simple calcium supplementation products, the calcium fertilizer provided by the invention is advantaged in good calcium supplementation effect and increased yield. The calcium fertilizer provided by the invention assists in promoting plant absorption and transportation of calcium, such that the calcium fertilizer can effectively solve the physiological calcium deficiency problems of fruit trees and vegetables. The calcium fertilizer can also be used for controlling various physiological diseases caused by calcium deficiency, such as apple bitter pox disease, pox blotch, pear blackheart, peach crevice line softening, dehiscent fruits of orange, litchi, longan, mango, dates, and watermelon fruit, umbilical rots of tomatoes and green peppers, cabbage dry heart, and other plant calcium deficiency diseases. With the calcium fertilizer provided by the invention, calcium content in fruits can be improved, the yield can be improved, the fruit quality can be improved, and the storage life can be prolonged.

Description

technical field [0001] The invention relates to a fertilizer and its application, in particular to a calcium-supplementing fertilizer and its application. Background technique [0002] As a nutrient element necessary for plant growth and development, calcium plays an extremely important role in plants. It is an indispensable element for the formation of the glue layer in the cell wall and is necessary for plant development. At the same time, it can maintain the integrity of the cell membrane, reduce respiration, and prevent cell aging. It can also promote the transport of photosynthetic products, prevent the poisoning of metal ions, and eliminate oxalic acid. Toxic to plants. . At the cellular level, it is a key signaling molecule in the plant cell stimulus-response signal transduction mechanism, involved in the regulation of reproductive growth and various stress defense responses, etc. In addition, the important role of calcium in programmed cell death has also been rec...
