Problems solved by technology

This method of additive increment not only seriously affects the normal growth of plants, but also makes the life span of plants less than 20 years, which is less than 1 / 3 of the normal life cycle.
In order to solve the problem, some places have used 2,4-D products to dilute the residual concentration of plants, but the result is counterproductive due to technical and safety reasons, so there is no safe and effective solution so far

Embodiment 1

[0017] Example 1 The residual amount of paclobutrazol in the soil is 30 mg / kg, and the cellulose content in the tree body is 35 mg / kg.

[0018] The mass ratio of each component in the safe degradation solution adopted is:

[0019] Gibberellin GAs 200mg / L, nitrogen 50g / L, calcium 50 g / L, potassium 100g / L.

[0020] The number of degradations used is 6 times, and the spraying interval is generally 20 days / time.

[0021] Spray the mixed solution evenly on the leaves and branches, because the above moderately residual trees are mainly sprayed with paclobutrazol, and at the same time, the same proportion of degradation solution is used to cut the soil and water the roots.

[0022] The first time of the whole spraying is about 20 days before the spring shoots of red bayberry plants, that is, one month before the young fruit stage in spring, to promote the long shoots of red bayberry plants. The second time is in the young fruit stage. In the third time, according to the paclobutra...

Embodiment 2

[0024] Example 2 The paclobutrazol residue in the soil is 20 mg / kg, and the cellulose content in the tree body is 25 mg / kg with moderate residual tree.

[0025] The mass ratio of each component in the safe degradation solution adopted is:

[0026] Gibberellin GAs 195mg / L, nitrogen 40g / L, calcium 45 g / L, potassium 95g / L.

[0027] The number of degradations used is 4 times, and the spraying interval is generally 30-45 days / time.

[0028] Spray the mixed liquid evenly on the leaves and branches. The first time of the whole spraying is about 20 days before the spring shoots of the red bayberry plants, that is, one month before the young fruit period in spring; thereafter, each interval is 40 days. Before the third spraying, the paclobutrazol residue index after the second spraying was detected and it was found that the degradation rate of the residual value was slow, so the concentration of the degradation solution and the ratio of each element were increased by 20%. During the ...

Abstract

The invention discloses safe degradation liquid for residue paclobutrazol in red bayberry plant bodies and a use method of the safe degradation liquid. All ingredients in the degradation liquid have the mass proportioning ratios as follows: gibberellin GAs is 180 to 220mg / L, nitrogen is 40 to 60g / L, calcium is 40 to 60g / L, and potassium is 90 to 110g / L. The safe degradation liquid designed according to the invention can be used for safely degrading residue paclobutrazol in red bayberry plants, so the red bayberry plants gradually recover the safe growth rule, the high-quality and health production requirements are reached, the fruit becomes safe and environment protection health food, and the potential safety risk of customers is eliminated.

Description

technical field [0001] The invention relates to a preparation for removing residues in red bayberry plants, in particular to a safe degradation liquid for residual paclobutrazol in red bayberry plants and a method for using the same. Background technique [0002] Due to the remarkable polar growth of bayberry plants, especially the large-fruited Dongkui bayberry, producers did not grasp the characteristics of the variety, resulting in serious plant size, cracked and rotten fruits, and some of them had flowers but no fruits for many years. In view of this, many farmers have transplanted the method of using paclobutrazol to dwarf and strengthen the seedlings of gramineous plants to suppress the shoots of bayberry, control the crown, and increase the yield per unit area. Although high yield can be guaranteed in that year, it will have a serious impact on tree life and product quality. If things go on like this, it will lead to more flowering, early flowering, more fruit, s...
