Abstract

The invention discloses a nutrient solution for preventing and treating chlorosis of a camphor tree. The nutrient solution comprises the following components in concentration by mass: 0.1-2 percent of water-soluble iron-contained compound, 0.01-0.1 percent of ethyoxyl modified polytrisiloxane and the balance of water. The invention also discloses a method for preventing and treating chlorosis of the camphor tree by the nutrient solution. The nutrient solution is applied to the camphor tree by a leaf surface spray method. The invention can effectively solve the phenomenon of the iron deficiency chlorosis of the camphor tree.

Description

technical field

[0001] The invention belongs to plant cultivation technology, and relates to a treatment method for iron-deficiency yellowing of camphor trees planted in calcareous or alkaline soil with pH>7.0, and a nutrient solution used for preventing and treating yellowing of camphor trees. Background technique

[0002] Camphor tree is also called camphor tree, wood camphor tree, black camphor tree, camphor tree, camphor tree, fragrant stamen, camphor tree, and belongs to the evergreen trees of Lauraceae. This tree species has dense branches and leaves, a large crown with thick shade, and a majestic tree posture. It can smoke and hold back dust, conserve water sources, fix soil and prevent sand, and beautify the environment. Plant. However, during the growth process of camphor trees, the phenomenon of "chlorosis and yellowing" of leaves and even the death of the whole plant generally exists, which seriously weakens the unique advantages and development of camphor tre...

Examples

Embodiment 1

[0024] Embodiment 1, a kind of nutrient solution of preventing and treating camphor tree yellowing, it is made up of the composition of following mass concentration: the ferrous sulfate of 0.20%, the ethoxyl modified polytrisiloxane surfactant of 0.031%, all the other are water.

[0025] The above three ingredients are simply stirred and mixed to obtain the nutrient solution for preventing and treating the iron-deficiency chlorosis of camphor trees.

[0026] Utilize the above-mentioned nutrient solution to prevent and treat the yellowed tender leaves of a camphor tree suffering from iron-deficiency chlorosis: spray the above-mentioned nutrient solution on both sides of the yellowed young leaves of the tree until the leaves are moist, and after spraying for 6 days The yellowed young leaves gradually turn green, and the green area reaches 45%, such as figure 1 Shown in A.

[0027] Contrast experiment 1, select for use and the suitable yellow leaves of camphor tree yellowing di...

Embodiment 2

[0028] Embodiment 2, a kind of nutrient solution of preventing and treating camphor tree yellowing, it is made up of the composition of following mass concentration: 0.18% urea iron, 0.028% ethoxyl modified polytrisiloxane surfactant, all the other are water .

[0029] The nutrient solution for preventing and treating camphor yellow disease is obtained by simply stirring and mixing the above three ingredients.

[0030] Utilize the above-mentioned nutrient solution to prevent and treat the new shoots of a camphor tree that has suffered from yellowing: spray the above-mentioned nutrient solution on some yellowed new shoots of the tree until the front and back of all leaves on the yellowed new shoots are wet, spray After applying for 7 days, all the yellowed tender leaves on the new shoots gradually regreened, and the regreened area reached 50%. figure 2 Shown in A.

[0031] Comparative experiment 2, with the same strain of embodiment 2 suffering from another part of new shoot...

Embodiment 3

[0032] Embodiment 3, a kind of nutrient solution of preventing and treating camphor tree yellowing, it is made up of the composition of following mass concentration: 0.25% EDTA-iron, 0.032% ethoxyl modified polytrisiloxane surfactant, all the other are water.

[0033] Utilize above-mentioned nutrient solution to prevent and treat a camphor tree suffering from iron-deficiency yellowing disease: spray above-mentioned nutrient solution on all yellowing new shoots of the tree, until the front and back of all leaves on the yellowing new shoots are all wet, spray 1 After a week, all the yellowed young leaves will gradually turn green again. Subsequently, it was sprayed once every 10 days and sprayed 3 times in a row, and the iron-deficiency chlorosis phenomenon of the tree disappeared.

[0034] Contrast experiment 3, select the camphor tree that suffers from iron deficiency chlorosis degree identical with embodiment 3 as reference object, be 0.25% EDTA-iron aqueous solution as nutr...
