Embodiment 1

[0052] The loquat tree thinning method of the present embodiment comprises:

[0053] (1) Observe the condition of the tree body: the ten-year-old five-star loquat tree has a strong tree vigor, and the flower-branch ratio is 70%.

[0054] (2) Preparation of flower thinning agent: take an appropriate amount of 98% naphthaleneacetic acid powder (active ingredient content is 98%), first dissolve in a small amount of 95% ethanol (naphthaleneacetic acid can be dissolved), and then make up to volume with water. According to Table 1, be prepared as the naphthaleneacetic acid solution of 10mg / L for subsequent use.

[0055] (3) Flower thinning: one week after the inflorescences bloom on more than 50% of the loquat canopy periphery, that is, one week after the full bloom period, use a sprayer to evenly spray 10mg / L naphthaleneacetic acid solution to the whole tree until each inflorescence has liquid dripping As the standard, adopt the principle of first up and then down, first outside a...

Embodiment 2

[0059] The loquat tree thinning method of the present embodiment comprises:

[0060] (1) Observe the condition of the tree body: a ten-year-old five-star loquat tree, the tree is weak, and the ratio of flowers and branches is 60%.

[0061] (2) Preparation of flower thinning agent: take an appropriate amount of 98% naphthalene acetic acid powder, dissolve it in a small amount of 95% ethanol and then dilute with water. According to Table 1, be prepared as the naphthalene acetic acid solution of 5mg / L for subsequent use.

[0062] (3) flower thinning: when more than 50% inflorescences of loquat crown periphery are in full bloom, i.e. the full bloom stage, use a sprayer to evenly spray the naphthalene acetic acid solution of 10mg / L to the whole tree, spray until each inflorescence has liquid dripping as the criterion, Adopt the principle of first up and then down, first outside and then inside, each tree is about 4L, and each inflorescence is 40mL.

[0063] (4) Preparation of fru...

Embodiment 3

[0067] The loquat tree thinning method of the present embodiment comprises:

[0068] (1) Observe the condition of the tree body: a ten-year-old five-star loquat tree, the tree vigor is moderate, and the flower-branch ratio is 55%.

[0069] (2) Preparation of flower thinning agent: take an appropriate amount of 98% naphthalene acetic acid powder, dissolve it in a small amount of 95% ethanol and then dilute with water. According to Table 1, be prepared as the naphthalene acetic acid solution of 5.5mg / L for subsequent use.

[0070] (3) Flower thinning: One week after the inflorescences of more than 50% of the periphery of the crown of the loquat tree are in full bloom, use a sprayer to evenly spray the 5.5mg / L naphthalene acetic acid solution to the whole tree, and spray until each inflorescence has liquid dripping. The principle of up and down, first outside and then inside, each tree is about 4L, and each inflorescence is 40mL.

[0071] (4) Preparation of fruit thinning agent...

Abstract

The invention discloses a loquat tree thinning method and a cultivation method of a loquat tree. The loquat tree thinning method includes the steps that 1, tree vigor is observed; 2, the flower and branch ratio is determined; 3, a flower thinning agent is sprayed according to the tree vigor and the flower and branch ratio. The thinning time of loquat flowers and fruits is reduced, the thinning difficulty is reduced, the thinning efficiency is effectively improved, the high cost of manual flower and fruit thinning is greatly reduced, the load of a tree body can be reasonably controlled, the strong tree vigor is kept, and flower bud differentiation of the next year is promoted.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting and cultivation, in particular to a loquat tree thinning method and a loquat tree cultivation method. Background technique [0002] The loquat tree has a long flowering period, a lot of nectar, a high fruit setting rate, and a large nutrient consumption. The relationship between growth and fruit is adjusted by thinning flowers and fruits. [0003] The big five-star loquat variety is a new variety of high-quality large-fruited loquat that was bred in Meiman Village, Longquanyi, Chengdu, Sichuan in 1978. Chongqing, Guangxi, Hunan, Jiangxi, Hubei and other places have large-scale cultivation. [0004] Big Five Star has a lot of flowers and fruit setting. If it is allowed to bloom and set fruit naturally, it will lead to weakening of the tree vigor, serious phenomenon of big and small years, small fruit and poor quality, and low commercial fruit rate. Therefore flower thinning and fruit ...
