Problems solved by technology

However, due to the special soil and water conditions and unreasonable cultivation measures in orchards in southern Xinjiang, 20-30% of the walnut orchards suffered from various degrees of physiological diseases, and the edges of the leaves turned yellow, brown, withered, shrunk, and appeared empty. The quality of kernels has seriously declined, the commodity rate is low, and the commodity rate of diseased walnut trees is only 50-70%. The economic loss caused by physiological diseases is as high as 1000-3000 yuan / mu, which seriously affects the healthy development of the walnut industry.

Embodiment

[0014] Take 10 parts by weight of salicylic acid, 200 parts by weight of betaine, 400 parts by weight of calcium nitrate, 2 parts by weight of indole acetic acid, and 100 parts by weight of fulvic acid, add the above-mentioned raw materials into 1000 parts by weight of water, fully stir and dissolve, and obtain this product. invention.

[0015] When in use, the product of the present invention is diluted 100 times with water, and the leaves are sprayed with a high-pressure sprayer in late May. Second-rate. .

[0016] The walnut "leaf edge scorch" physiological disease prevention and control agent of this embodiment was applied in the walnut orchard of Gayitireke Village, Luopu Town, Luopu County, Hotan District, Xinjiang in 2012, and the obtained effect (compared with water spray) data is as follows:

[0017] The rate of diseased leaves of walnut trees decreased by 45.3%, the ratio of leaf scorch area decreased by 63.6%, the rate of black shrunken fruit decreased by 44.8%, a...

Abstract

The invention discloses a 'leaf margin' physiological disease prevention and control agent for walnuts and belongs to the technical field of nutrition regulation. The prevention and control agent comprises salicylic acid, glycine betaine, calcium nitrate, heteroauxin, fulvic acid and water. The 'leaf margin' physiological disease is caused by the fact that sodions and chloridions accumulate excessively on leaves of the walnuts and harm is caused for cells. The salicylic acid, the glycine betaine and the heteroauxin can regulate ion absorption, the calcium nitrate can prevent sodions from absorbing and can maintain the structure of a cell membrane, the fulvic acid can restrain transpiration and prevents the sodions and the chloridions from being conveyed upwards, all substances are matched, and the harm of the sodions and the chloridions for the walnuts is reduced.

Description

technical field [0001] The invention belongs to the technical field of nutrition regulation, and in particular relates to an agent for preventing and controlling the physiological disease of walnut "leaf margin scorch". Background technique [0002] The walnut planting area in southern Xinjiang has reached more than 3 million mu, and walnut production has become a pillar industry for local farmers to increase their income. However, due to the special soil and water conditions and unreasonable cultivation measures in orchards in southern Xinjiang, 20-30% of the walnut orchards suffered from various degrees of physiological diseases, and the edges of the leaves turned yellow, brown, withered, shrunk, and appeared empty. The quality of kernels has seriously declined, and the commercial rate is low. The commercial rate of diseased walnut trees is only 50-70%. The economic loss caused by physiological diseases is as high as 1000-3000 yuan / mu, which seriously affects the healthy d...
