The plant growth regulator is used for promoting the flower of mango.
The application method of the plant growth regulator provided by the invention comprises the steps of stopping growth at the No. 2 top of mango, spraying the leaf surface by using a sprayer after the leaf is aged, continuously spraying for 3 times at intervals of 3 days, and preferably spraying moisture.
The spraying concentration mg/L of the active ingredients of the plant growth regulator provided by the invention is as follows: 32-100 parts of thidiazuron, 6-15 parts of naphthylacetic acid, 6-15 parts of compound sodium nitrophenolate, 6-15 parts of brassinolide and 6-15 parts of diethyl aminoethyl hexanoate. The spraying concentration mg/L of the preferable active ingredients is as follows: thidiazuron 32, naphthylacetic acid 6, compound sodium nitrophenolate 6, brassinolide 6 and diethyl aminoethyl hexanoate 6.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention combines and uses thidiazuron, naphthylacetic acid, compound sodium nitrophenolate and brassinolide, or thidiazuron, naphthylacetic acid, compound sodium nitrophenolate, brassinolide and diethyl aminoethyl hexanoate, and has good synergistic effect on promoting germination and formation of flower buds;
2. the plant on-regulating agent can obviously improve the germination rate and the proportion of flower buds of mango, and effectively improve the yield of mango;
3. when thidiazuron, naphthylacetic acid, compound sodium nitrophenolate, brassinolide and diethyl aminoethyl hexanoate are adopted for treatment, the germination rate of mangoes is over 80 percent, and the proportion of flower buds is over 90 percent. In particular, treatment 3 was the optimum concentration combination, with a germination rate of 89.09; and the proportion of flower buds is as high as 94.56%.
Detailed Description
The invention will be better understood from the following examples. However, those skilled in the art will readily appreciate that the description of the embodiments is only for illustrating the present invention and should not be taken as limiting the invention as detailed in the claims.
Example 1: test of flower forcing effect
And (3) test crops: tainong No. one
Test materials: thidiazuron, naphthylacetic acid, compound sodium nitrophenolate, brassinolide and diethyl aminoethyl hexanoate; are all commercially available.
The test method comprises the following steps: and (3) stopping growing of the No. 2 sprout, and spraying the leaves by using a sprayer after the leaves are aged, wherein the spraying is carried out for 3 times continuously, and the spraying is preferably carried out for 3 days. Checking the flower forcing effect, and when the bud length is more than 1cm, considering that the bud is germinated.
The statistical method comprises the following steps: the tooth eruption rate is (number of eruption/total number of buds) × 100%; the flower bud ratio is (pure flower bud + mixed bud)/(pure flower bud + mixed bud + leaf bud) × 100%.
Table 1: the flower forcing effect of different components on mangoes
As can be seen from Table 1, when the brassinolide, thidiazuron and diethyl aminoethyl hexanoate are singly adopted or treated by thidiazuron, naphthylacetic acid and compound sodium nitrophenolate, the budding rate is low and is only 55.88%, 50.29%, 66.67% and 60.00%; and the proportion of leaf buds is high, which seriously influences the yield of the mangoes.
When the thidiazuron, the naphthylacetic acid, the compound sodium nitrophenolate and the brassinolide are adopted for treatment, the germination rate of the mango is obviously improved compared with that of a single agent or a ternary combination, the proportion of leaf buds is obviously reduced, and the yield of the mango can be effectively improved.
When thidiazuron, naphthylacetic acid, compound sodium nitrophenolate + +, brassinolide and diethyl aminoethyl hexanoate are adopted for treatment, the germination rate of mangoes is over 80 percent, and the proportion of flower buds is over 90 percent. In particular, treatment 3 was the optimum concentration combination, with a germination rate of 89.09; and the proportion of flower buds is as high as 94.56%.
Example 2: formulation of dosage forms
12.5% wettable powder
