Embodiment 1
[0013] Embodiment 1: a kind of method that promotes walnut frost damage back flowering and fruit setting, comprises the steps: when walnut male flower bud and fruiting branch are annual branch terminal buds, or male flower bud and fruiting branch are the year-old twig pruning froze to death, The walnut trees are sprayed with tree body growth recovery liquid; at the flowering stage of the mixed buds on the walnut side, the walnut pollen water suspension is sprayed on the walnut trees; when the walnut fruit expands, the fruit-setting nutrient solution is sprayed. The tree growth recovery liquid is mixed with water, vitamin C of 0.02% water weight, tea polyphenols of 1.0% water weight and thiophanate-methyl of 0.15% water weight; Water is mixed in a weight ratio of 1:4000; the fruit-setting nutrient solution is composed of water, ferrous sulfate of 0.25% water weight, urea of 0.15% water weight, borax of 0.1% water weight, and dihydrogen phosphate of 0.1% water weight Potassium...
Embodiment 2
[0014] Embodiment 2: a kind of method for promoting flowering and fruit setting after frost damage of walnut, comprises the steps: when male flower bud and fruiting branch promptly live in the year when young shoot top or young fruit freeze to death, cut off all new shoots, walnut tree is sprayed with tree body growth recovery Spray the walnut pollen aqueous suspension on the walnut tree at the mixed bud flowering stage on the walnut side; spray the fruit-setting nutrient solution when the walnut fruit expands. The tree growth recovery liquid is mixed with water, vitamin C of 1.0% water weight, tea polyphenols of 0.01% water weight and thiophanate-methyl of 0.02% water weight; Water is mixed by 1: 6000 weight ratio; Described fruit-setting nutrient solution is by the ferrous sulfate of water, 0.001% water weight, the urea of 0.3% water weight, the borax of 0.3% water weight, the dihydrogen phosphate of 0.05% water weight Potassium blend. The spraying rates of the tree growt...
Embodiment 3
[0015] Embodiment 3: a kind of method of promoting flowering and fruit setting after walnut frost damage, comprises the steps: when walnut male flower bud and fruiting branch are annual branch top buds, or male flower bud and fruiting branch are the year-old twig pruning froze to death, The walnut trees are sprayed with tree body growth recovery liquid; at the flowering stage of the mixed buds on the walnut side, the walnut pollen water suspension is sprayed on the walnut trees; when the walnut fruit expands, the fruit-setting nutrient solution is sprayed. The tree growth recovery liquid is mixed by water, vitamin C of 0.5% water weight, tea polyphenols of 0.05% water weight and thiophanate-methyl of 2.0% water weight; Water is mixed in a weight ratio of 1:2000; the fruit-setting nutrient solution is composed of water, ferrous sulfate of 0.12% water weight, urea of 0.1% water weight, borax of 0.2% water weight, and dihydrogen phosphate of 0.2% water weight Potassium blend. ...
