Technical Field

The invention belongs to a plant bud removing agent, and particularly belongs to a kiwi fruit bud removing agent and application thereof.

Background

The kiwi fruit is rich in vitamins and various amino acids, has palatable sweetness and sourness and special flavor, and is known as the king of fruit. At present, the Chinese kiwi fruit cultivation area and yield are all in the world 1 st, account for about 50% of the world yield, far exceed the world Kiwi fruit main-producing countries Italy, Turkey, New Zealand, Chile and the like, become agricultural support industries with the demerit and the richness of farmers in counties and cities of Shanxi Mei county, Zhou, Henan Xixia, Jiangxi Fengxin New county and the like in China, and also become important components of Jiangsu leisure sightseeing and harvesting agriculture. In the near stage, with the change of consumption concept and consumption demand of people in China, the kiwi fruit industry can be developed more rapidly.

Bud picking, particularly for the trunk bud picking of 1-3 year old kiwi fruit trees, is one of the conventional measures which must be taken for production management of kiwi fruits. At present, the bud picking method is mainly carried out in an artificial mode, the bud picking mode is easy to cause wounds at the bud picking position of the kiwi fruit to cause germ invasion, and particularly, branch canker is easy to occur in non-ulcer-resistant varieties such as red yang and the like; there are also reports of bud removal using chemical methods, but it is not considered that buds remaining on the branches can easily cause infection of germs to cause secondary damage.

Disclosure of Invention

According to the invention, the contact herbicide and the bactericide are mixed for use, and the bud eyes of the kiwi fruit which initially germinates are sprayed, so that on one hand, the effect of bud removal can be achieved, the generation of wounds at the bud eyes is avoided, on the other hand, the infection of withered buds by germs can be avoided, and the secondary damage is reduced.

The invention provides a kiwi fruit bud remover which consists of a contact herbicide and a bactericide. The contact herbicide is a glufosinate-ammonium aqua, and the bactericide is kresoxim-methyl suspending agent.

The preferred concentration of the glufosinate-ammonium aqueous solution is 200g/L, and the dosage is 4500-²(ii) a The concentration of the kresoxim-methyl suspending agent is 250g/L, and the dosage is 900-1350mL/hm²。

The more preferable concentration of the glufosinate-ammonium aqueous solution is 200g/L, and the dosage is 6000mL/hm²(ii) a The concentration of the kresoxim-methyl suspending agent is 250g/L, and the dosage is 1245mL/hm²。

The invention also provides a use method of the bud removing agent, which comprises the following steps: mixing the bud removing agent according to the dosage to form a liquid medicine, and directionally spraying the liquid medicine on the bud to be removed of the main part of the kiwi fruit by using a knapsack sprayer until the liquid medicine is about to drop.

The preferred application method of the invention is as follows: the spraying time of the method is from the germination period of the kiwi fruits to the initial expansion of 1-2 leaves.

The bud remover disclosed by the invention is applied to the gray mold of kiwi fruits, so that buds which do not fall off timely are prevented from being infected by germs such as gray mold and the like.

Has the advantages that: according to the method, the bud of the kiwi fruit trunk is removed by using the contact herbicide and the bactericide in a mixing manner, so that the redundant buds which do not need to be reserved in the trunk can be effectively removed, the wound caused by artificial bud picking is reduced, and the germ infection caused by using a chemical bud removing method singly can be effectively avoided.
