Description

Soluble composition and preparation method and application thereof

Technical Field

The invention belongs to the technical field of plant growth regulators or pesticide preparations, and particularly relates to a soluble solution composition and a preparation method and application thereof.

Background

The uniconazole or the paclobutrazol has obvious regulation effect on the physiological characteristics of plants, can obviously reduce the plant height of grain crops such as rice, wheat, corn or soybean, obviously thicken basal stalks, obviously enhance the lodging resistance, has wide application in lodging resistance and stable yield of the grain crops such as rice, wheat, corn or soybean, but is found to have the risk of reducing the yield of the grain crops under the condition that the contrast does not generate lodging (the probability of occurrence of lodging of the crops has close relation with the weather conditions of cultivation and season).

One of the remarkable characteristics of the plant growth regulator is that the effective components of the plant growth regulator must be fully absorbed by crops and enter into the cell for reference and physiological and biochemical metabolism to play a powerful regulating and controlling role. However, as the original medicines of the uniconazole and the paclobutrazol are insoluble in water, the existing medicines are used in a wettable powder formulation, and the dosage per mu is large and the utilization efficiency is low. Meanwhile, the problem of increased environmental pressure and the like caused by the addition of a large amount of harmful auxiliary agents during the processing of the wettable powder of uniconazole or paclobutrazol. For example, the effective content of the wettable powder of uniconazole and paclobutrazol used in production is generally 5% of the wettable powder of uniconazole and 10% of the wettable powder of paclobutrazol, the effective component dosage before the jointing period of paddy rice and wheat is respectively 2-5 g/mu and 5-10 g/mu, and various auxiliary agents are added about 90 g/mu. When the wettable powder is mixed with water and sprayed on leaf surfaces, a great amount of raw medicine components are trapped on the surfaces of crop leaves or stems because true solution is not formed and the true solution enters the inside of cells through pores, epidermal cells and the like, so that a great amount of raw medicine components can be trapped on the surfaces of the crop leaves or stems, and then enter soil along with rainwater spraying to form a great environmental pressure, adverse effects are generated on the soil environment, and the damage to next crops can be caused when serious. In order to better solve the problem of high-efficiency utilization of uniconazole or paclobutrazol, the uniconazole or paclobutrazol is transformed into a soluble composition which is easy to be absorbed and utilized by crops, so that the utilization efficiency of uniconazole or paclobutrazol substances is improved, the actual use amount is reduced as much as possible, and the side effect is reduced.

⑥ Spraying clear water for comparison.

The VB4 dose in the treatment ③～④ was 18 g/mu of 80% VB4 (i.e., vitamin B4).

4. Checking the indexes:

(1) Plant height (cm); (2) spikes per mu; (3) the number of solid grains per ear; (4) thousand grain weight (g); (5) cell yield (kg/mu).

TABLE 15 test of water-soluble vitamins for reducing side effects of uniconazole (paclobutrazol) Nanjing 45

From table 15, it can be seen that: 1. VB4 is sprayed alone to have little influence on plant height and spike formation per mu, but has a trend of increasing the number of grains per spike, thousand grain weight and yield, and the average yield is increased by more than 4%. 2. The soluble solutions of uniconazole and paclobutrazol are respectively reduced in yield by 5.02% and 6.99% in the jointing period spraying without adding VB 4. However, the vitamin VB4 substances are added to increase the yield by 3.13% and 3.08% respectively; the soluble solutions of uniconazole and paclobutrazol are also reduced in yield by 2.6% and 4.26% respectively when sprayed in the initial spike period without adding VB 4. However, the vitamin VB4 substances are added to increase the yield by 5.34% and 6.44% respectively. The side effects of the soluble agents of uniconazole and paclobutrazol can be obviously reduced after the water-soluble vitamin VB4 is added.

Table 16 Regulation and synergism of phytic acid on uniconazole and paclobutrazol soluble solution is compared with that of Nanjing 45

From table 16, it can be seen that:

1. The phytic acid has the effect of obviously improving the regulation and control effects of the uniconazole and the paclobutrazol in a soluble state. The treatment ①② (adding phytic acid) respectively reduces the plant height by 10.9 percent and 8.8 percent in the jointing period spraying and reduces the average by 9.85 percent. The average decrease of treatment ④⑤ (no phytic acid) was only 2.01%, and the spraying of phytic acid alone (treatment ③) had no decrease in plant height (0.39% increase and 0.29% increase in the jointing period and the spike period compared with the control).

2. The base 1-2 internode length. Under the condition that the uniconazole and the paclobutrazol are added in the phytic acid, the spraying average time in the jointing period is shortened by 5.16cm and reaches 41.6%, and the length of 1-2 joints of the base part of the treatment ③ (only spraying the phytic acid) is unchanged, which shows that the adding of the phytic acid can obviously improve the effect of the uniconazole and the paclobutrazol soluble agent in shortening the length of the joints of the base part of the rice.

3. The second internode fracture resistance and fullness of the basal part are obviously improved after the phytic acid is added, whether the basal part is sprayed in the jointing stage or the spike starting stage. The average breaking strength and the fullness of the jointing period treatment ①② are respectively improved by 54.16 percent and 22.85 percent compared with the contrast, and the spraying at the initial spike period is respectively improved by 56.35 percent and 43.2 percent; and the spraying of the jointing period is respectively improved by 20.65 percent and 11.05 percent without the treatment ④⑤ of adding phytic acid. The spraying at the initial spike period is respectively improved by 10.0 percent and 20.76 percent. The spraying of the treatment ③ only in the phytic acid jointing period is respectively improved by 1.9 percent and 3.71 percent, and the spraying in the spike starting period is only improved by 0.14 percent and 3.16 percent.

4. From cell yield analysis. The uniconazole and the paclobutrazol can obviously reduce the risk of yield reduction after the phytic acid chelating stabilizer is added; the average yield can be increased by 3.9 percent by independently spraying the phytic acid; however, the spraying of the plant acid in the initial spike period has obvious yield increasing effect, the average yield of the treatment ①② is increased by 7.0 percent, and the average yield is reduced by 2.3 percent without the addition of the plant acid; the average yield reduction of spraying in the jointing period is about 5% without adding phytic acid, and the average yield increase is about 2.5% after adding phytic acid.

5. The present test also shows that ethanol, methanol, or a combination of both can be used as solvents for uniconazole and paclobutrazol.

Although the foregoing embodiments have been described in some, but not all, embodiments of the invention, it should be understood that other embodiments may be devised in accordance with the present embodiments without departing from the spirit and scope of the invention.
