Description
Technical Field
The invention relates to the technical field of plant growth regulators, in particular to a plant growth regulating composition, a preparation, an application and an application method.
Background
Higher plants almost have top advantages in their growth. The growth of the stem, the root, the lateral bud and the lateral root of the plant is inhibited by the growth of the main stem and the main root; when the main stem and the main root are removed, the lateral bud and the lateral root can grow without limitation, and the phenomenon is called as apical dominance. For example, cotton has the characteristic of unlimited growth, has obvious apical dominance, and can continuously grow upwards and simultaneously continuously differentiate new branches, stems and leaves under the condition of environment suitable. The growth of the main stem, ineffective buds, bolls and branches with unlimited growth consumes nutrients, so that the nutrition of plants is declined, and the growth and development of effective fruits are further influenced.
Pruning and topping are a technology for removing apical dominance, promoting reproductive growth and improving yield. The topping can control the longitudinal growth of the main stem, reduce the plant height, reduce the growth of ineffective nutrition, play a great role in the growth and development of reproductive organs, and can adjust the nutrient transmission direction of the plant body by timely and vigorously topping, so that more nutrients are transported to flowers and fruits and roots, the generation of ineffective flowers and fruits is reduced, and the effect of increasing the yield is obvious. The traditional topping is to manually nip and remove main stem growing points or trim branches, and the method has the defects of low production efficiency, high labor cost, large consumption of manpower and material resources and missing topping. Although the mechanical topping efficiency is high, the mechanical damage to plants is large, and the normal growth of the plants is not facilitated.
The chemical topping-free technology utilizes plant growth regulating substances to inhibit the growth of plant tops, group tops and vegetative branches, thereby achieving the purpose similar to artificial topping. The plant growth regulator can be sprayed in the field by machinery, so that the labor intensity can be reduced, the topping efficiency can be improved, and the labor cost can be saved. In recent years, chemical topping, shoot control and vigor control technologies using plant growth regulators such as mepiquat chloride, chlormequat chloride and paclobutrazol have been widely used in production.
The plant growth regulator is artificially synthesized chemical matter with plant growth regulating effect and natural plant hormone extracted from organism. At present, many plant growth regulators are used alone, often cannot achieve ideal effects, and have certain defects or bring certain side effects: if the biological activity is single, the growth regulation effect is relatively low, and generally the plant can only play a limited role in a certain growth period of crops. For example, the mepiquat chloride is a commonly used plant growth regulator in agricultural production, and can inhibit the overgrowth of stems and leaves, control lateral branches and shape an ideal plant type, so that the number and the activity of plant roots are improved, the reproductive growth of plants is promoted, the weight of fruits is increased, and the quality of the fruits is improved; the fertilizer is widely applied to crops such as cotton, wheat, rice, peanuts, corns, potatoes, grapes, vegetables, beans, flowers and the like. However, the current mepiquat chloride is generally used for a plurality of times in a single dose, and the problems of unstable drug effect, poor effect of inhibiting the growth of axillary buds, need to be used for a plurality of times, easy induction of the greedy and late maturity of crops and the like exist in the use of the mepiquat chloride.
With the continuous improvement of the automation and mechanization degree of modern agriculture, the market demand for novel chemical topping and tip control products with stable action effect and good crop safety is increasing, and the invention is especially provided in view of the above.

The test field is close to the well house, the cotton grows vigorously, and the water and fertilizer of the whole cotton field are normally managed. The test cells are arranged in unidirectional random blocks, and each cell has an area of 30m 2 4 repeats.
The plant growth regulator preparations and compositions prepared in examples 1 to 4 were sprayed on the stems and leaves of cotton in the full-bloom stage (when 3 to 4 fruit branches bloom) of 7 months and 8 days, respectively, as single agents and control agents 1 and 2 (comparative examples 1 and 2), and the amount of the sprayed liquid (added with water) was 450L/ha. The water and fertilizer chemical control is carried out according to normal management without additional control. Recording the soil type, meteorological data, insect control, disease prevention and other field management conditions of the test field. After the application of the pesticide, whether the cotton of the target crop has abnormal (symptoms such as yellowing, twisting and shrinking) or not and whether the apical bud continues to grow or not are regularly observed. The plant height and fruit set of each treatment were investigated at 7 days 9 months, and the capping rate was visually observed, and the yield was measured at the time of cotton harvesting, and the results are shown in Table 4.
TABLE 4 comparison of agronomic traits and yields in field plot experiments
As can be seen from Table 4, the plant heights and fruit tops of the treatments of examples 1-4 are substantially the same as those of comparative examples 1-2 and single agents 5-7, and are lower than those of the clear water control but higher than those of the manual topping treatment; the safety of each treatment of examples 1 to 4 and each single agent 5 to 7 on other tissues such as cotton leaves, young buds and the like is obviously higher than that of comparative examples 1 to 2; examples 1-4 were visually rated for higher capping than comparative example 2 and single dose comparative examples 5-7, which are essentially equivalent to comparative example 1; the yield of the ginned cotton measured by the examples 1-4 is basically higher than that of the cotton fields treated by the single-dose comparative examples 5-7 and the comparative examples 1-2 and artificially topped, the chemical capping effect is good, and the yield is obviously increased; compared with the example 2, the application amount of mepiquat chloride and the application amount of aminotrifluralin are consistent, the application amount of ethephon is increased by 60 g/hectare in the example 4, and the test result shows that the plant height, the fruit table and the capping rate are basically consistent, but the yield of the plant is obviously higher than that of the plant, and the yield increasing effect is obvious after ethephon is added.
The field observation shows that comparative example 1 has serious phytotoxicity of top tender leaf shrinkage, the later part can recover, comparative example 2 has the phenomena of top sealing fastness (the visual capping rate is only 83.2 percent), cotton regrowth in the later part and early senescence of middle and lower leaves, and examples 1-4 do not have the phenomena. It can be seen that after the plant growth regulator provided in examples 1-4 is sprayed, the bifloran, mepiquat chloride and ethephon binary or ternary composition are applied under the condition of no deliberate water and fertilizer control, the cotton is better in safety due to synergistic cooperation, the chemical capping rate and the yield are higher than those of the common control topping agents for cotton fields, the effect is more stable, and the yield increasing effect of the ternary composition added with ethephon is more obvious.
