Walnut foliar fertilizer for promoting flowers and protecting fruits

Abstract

The invention provides a walnut foliar fertilizer for promoting flowers and protecting fruits. The walnut foliar fertilizer for promoting flowers and protecting fruits is mainly produced from Oscillatoria princeps, Porphyridium cruentum, Petunia hybrid, Rhizoma Paridis, Chinese asafetida, ginseng filter residues, plant ash, potassium fulvate, Zornia gibbosa, smallflower bracketplant herb and Doellingeria scaber (Thunb.) Nees. A preparation method of the walnut foliar fertilizer concretely comprises the following steps: extracting the Oscillatoria princeps, Porphyridium cruentum, Petunia hybrid, Rhizoma Paridis, Chinese asafetida, ginseng filter residues, plant ash, Zornia gibbosa, smallflower bracketplant herb and Doellingeria scaber (Thunb.) Nees with water, and taking obtained filtrate; heating the filtrate to 20-30 DEG C by using weak heat, pouring potassium fulvate into the filtrate, and stirring potassium fulvate and the filtrate for 30 min to obtain a mixed solution; and concentrating the mixed solution, and drying the obtained concentrate to prepare powder which is the foliar fertilizer. The foliar fertilizer can dispel insects, kill insects and kill bacteria, and also has the advantages of reduction of the use amount of pesticides, substantial flower protecting, fruit protecting and yield increasing effects, plump fruits, and good quality.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of fertilizers, and in particular relates to a walnut foliage fertilizer for promoting flowers and preserving fruits. [0003] 【Background technique】 [0004] Flower and fruit drop is common in plants, especially fruit trees. Fruit shedding is a natural phenomenon to a certain extent. An appropriate amount of fruit shedding is beneficial to the production and development of plants, but too much shedding brings serious economic losses to crops and fruits and vegetables whose main products are fruits. Walnut is an important nut tree species and a traditional export fruit in my country. However, the output of walnut has been low and unstable. One of the reasons is that the rate of flower and fruit drop is relatively high, generally 30% to 50%, up to 80%, resulting in major Yield loss.

The shedding of fruit is a natural phenomenon to a certain extent. A moderate amount of fruit shedding is beneficial to the production and development of plants, but too much shedding brings serious economic losses to crops and fruits and vegetables whose main products are fruits.

Walnut is an important nut tree species and a traditional export fruit in my country. However, the output of walnut has been low and unstable. One of the reasons is that the rate of flower and fruit drop is relatively high, generally 30% to 50%, up to 80%, resulting in major yield loss

[0005] The main reasons for falling flowers and fruits are as follows: 1. Severe pests and diseases, which directly consume a large amount of nutrients of fruit trees, resulting in insufficient supply of nutrients for flowers and fruits; 2. Defertilization of the soil, insufficient soil fertilization or partial application of certain fertilizers Lead to soil defertilization, which in turn manifests as fruit tree deficiency

Generally, fruit farmers pay more attention to the combined application of nitrogen, phosphorus, and potassium fertilizers, but they are easy to ignore some trace element fertilizers, such as boron, iron, calcium, etc., and these trace elements have a good effect on the flower preservation and fruit stability of fruit trees; 3. Flowering period There is a lot of rain, especially in the south of our country. Many fruit trees are prone to long-term continuous rainy weather during the flowering period, which has a greater impact on the vitality of pollen and causes more flowers to fall off early

In addition, too much rain will cause the soil to be too wet, which will affect the absorption of soil nutrients by the roots of fruit trees and aggravate the occurrence of flower drop; 4. Excessive use of insecticides during the flowering period of fruit trees will kill many insects and affect insects' flowering and pollination. Aggravate the falling of fruit trees
