Problems solved by technology

2) If the leaves decline early, they will not be able to produce and store nutrients for the tree well, resulting in weak assimilation function, low accumulation level, and poor material conditions to promote the growth and development of the tree in the coming year, which will inevitably lead to germination, flowering, fruit setting and Young fruit development is greatly affected
3) Due to the premature senescence and fall of the leaves and the low leaf area index, the normal physiological functions of the tree body such as respiration, transpiration, absorption, and storage are limited, which greatly reduces the stress resistance of the tree body. Outbreaks of spring rot and dry rot

[0024] A leaf-preserving agent for preventing early defoliation of apple trees, including Ce(NH 4 ) 2 (NO 3 ) 6 , polyethylene glycol, 8-hydroxyquinoline and a complex plant extract, the plant complex extract is a complex extract of licorice leaf, pecan leaf and primrose. Wherein the proportion of each component in the leaf-preserving agent in parts by weight is: Ce(NH 4 ) 2 (NO 3 ) 6 5 parts, 15 parts of polyethylene glycol, 2 parts of 8-hydroxyquinoline, 10 parts of plant compound extract.

[0025] The preparation method of the plant compound extract used in this example is:

[0026] (1) According to the weight ratio of fresh licorice leaves, fresh pecan leaves and fresh primrose petals:

[0027] Licorice leaves: Pecan leaves: Primrose petals = 1:3:2,

[0028] Mix and mash, then soak the mash in water and boil, wherein the quality of the water is 3 times the mass of the mixed mash, the boiling time is 10min, after boiling, it is cooled to room temperature, and the s...

[0033] A leaf-preserving agent for preventing early defoliation of apple trees, including Ce(NH 4 ) 2 (NO 3 ) 6 , polyethylene glycol, 8-hydroxyquinoline and a complex plant extract, the plant complex extract is a complex extract of licorice leaf, pecan leaf and primrose. Wherein the proportion of each component in the leaf-preserving agent in parts by weight is: Ce(NH 4 ) 2 (NO 3 ) 6 7 parts, 17 parts of polyethylene glycol, 4 parts of 8-hydroxyquinoline, 10 parts of plant compound extract.

[0034] The preparation method of the plant compound extract used in this example is:

[0035] (1) According to the weight ratio of fresh licorice leaves, fresh pecan leaves and fresh primrose petals:

[0036] Licorice leaves: Pecan leaves: Primrose petals = 1:4:2,

[0037] Mix and mash, then soak the mash in water and boil, wherein the quality of the water is 3 times the mass of the mixed mash, the boiling time is 10min, after boiling, it is cooled to room temperature, and the s...

Embodiment 3

[0042] A leaf-preserving agent for preventing early defoliation of apple trees, including Ce(NH 4 ) 2 (NO 3 ) 6 , polyethylene glycol, 8-hydroxyquinoline and a complex plant extract, the plant complex extract is a complex extract of licorice leaf, pecan leaf and primrose. Wherein the proportion of each component in the leaf-preserving agent in parts by weight is: Ce(NH 4 ) 2 (NO 3 ) 6 8 parts, 17 parts of polyethylene glycol, 6 parts of 8-hydroxyquinoline, 10 parts of plant compound extract.

[0043] The preparation method of the plant compound extract used in this example is:

[0044] (1) According to the weight ratio of fresh licorice leaves, fresh pecan leaves and fresh primrose petals:

[0045] Licorice leaves: Pecan leaves: Primrose petals = 1:5:2,

[0046] Mixing and mashing, then soaking the mashed material in water and boiling, wherein the quality of the water is 3 times the mass of the mixed mashed material, the boiling time is 10~20min, after boiling, it is ...

Abstract

The invention discloses a leaf-protecting agent for preventing apple trees from falling leaves in early stage. The leaf-protecting agent comprises Ce(NH4)2(NO3)6, polyethylene glycol, 8-hydroxyquinoline and plant compound extract, wherein the plant compound extract is a compound extract of liquorice leaves, hickory leaves and primroses. The self-made leaf-protecting agent for preventing apple trees from falling leaves in early stage disclosed by the invention is capable of obviously improving the phenomenon of fallen leaves of apple trees; compared with the traditional leaf-protecting agent formula including 8-hydroxyquinoline, polyethylene glycol and alpha-naphthylacetic acid, the leaf-protecting agent disclosed by the invention has the advantages that the leaf protection rate of apple trees is obviously increased; the branches and leaves of apple trees are denser when mature apples are picked, so that the yield of apples is correspondingly increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation and planting, in particular to a leaf-preserving agent for preventing early defoliation of apple trees and a method for using the same. Background technique [0002] In recent years, the phenomenon of premature senescence and early fall of apple tree leaves is quite common. In some apple orchards, the susceptibility rate of early defoliation disease is as high as 100%, which brings undue economic losses to fruit farmers. Production practice shows that the preservation of apple tree leaves cannot be ignored. Generally speaking, the meaning of apple leaf preservation is: 1) The leaves are the main organ that uses photosynthesis to produce organic nutrients. 90% of the dry matter in plants is synthesized by leaves. The activity of leaves is the material basis for the growth and development of fruit trees, flowering and fruiting. Especially in autumn, the quantity and quality of leaves...
