Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the following embodiments.
The invention firstly provides a pepper yield-increasing combination, which comprises a plant growth regulator; the plant growth regulator comprises uniconazole and triacontanol.
In the process of flower bud germination of the pepper, the germination and flower bud differentiation are easily promoted, the flower bud of the pepper gradually germinates from the morphological upper end to the morphological lower end of the branch, so that nutrient supply in the later period of flower bud germination is insufficient, the flower bud at the lower end falls off, the normal growth cannot be realized, and the yield is reduced.
In the pollination and fruit setting period of the pepper in the flowering period, if the nutrient supply is insufficient, the pollen development is influenced, and further the fertilization is influenced. A great deal of physiological fruit drop also occurs after flower withering.
In the trimming period after fruiting of the pepper, when the growth of the branches of the fruits is controlled, in order to improve the fruit setting capacity of the pepper, after the pepper is picked, the whole tree is trimmed, so that the pepper sprouts to give new tips at the later stage, the growth of the new tips can be continued from summer to winter, and the processes of sprouting, branch extension, branch aging, flower bud differentiation and nutrient storage of the branches need to be completed in a short half year. The process has more physiological changes and is very easily influenced by natural conditions, so that the flower bud differentiation and nutrient accumulation processes are blocked, and the yield increasing effect is influenced.
The matching use of the plant growth regulator with different functions and the functional fertilizer, and the single use of the plant growth regulator and the functional fertilizer in the critical period of the growth of crops can enlarge the action range, improve the pesticide effect, reduce the use risk and effectively reduce the use amount of pesticides. This technology has become one of the major development directions and key technologies in the plant growth regulator industry.
Uniconazole belongs to a plant growth retardant, can properly inhibit the growth of young shoots, slows down the growth of branches and shortens the space between leaves; meanwhile, the uniconazole reduces the catalase content in the plant body, thereby delaying cell senescence, increasing the green content of leaves in the plant body, improving photosynthesis, promoting dry matter accumulation to ensure a large amount of nutrition required by flower bud differentiation, and externally showing that the leaves are deepened and thickened.
Triacontanol belongs to a reproductive growth promoter, is mainly used for promoting the reproductive growth of pepper fruit branches, and can increase the number of leaves by promoting cell division, further improve the chlorophyll content, enhance photosynthesis, further improve the protein content in plants, achieve the purposes of promoting germination and differentiation and further improve the flowering number.
Through the combined action of the plant growth retardant and the reproductive growth promoter, the nutrient distribution is reasonably regulated and controlled in the vigorous growth period of the new tips of the peppers, the nutrient accumulation is promoted, and meanwhile, the monopotassium phosphate is supplemented to provide a large amount of nutrient reserves for reproductive growth, so that the cell division is promoted, the number of leaves is increased, the differentiation of flower buds is increased, and the effect of improving the yield is achieved. When the application time is studied, researchers unexpectedly find that when the average length of the pepper in autumn is 60-70 cm, the plant growth retardant and the reproductive growth promoter are simultaneously used under a specific concentration, the length of branches of the pepper in autumn can be shortened to the maximum extent, lignification of the branches is promoted, growth of lateral branches of the pepper in autumn is inhibited, the number of leaves of the pepper in autumn is increased, dry matter accumulation is improved, flower bud differentiation of bearing branches is promoted, and the effect of improving the yield of the pepper is achieved.
In order to better realize yield increase, the plant growth regulator comprises the following components in parts by weight: 200 portions of uniconazole and 0.5 to 2.0 portions of triacontanol.
In order to further realize yield increase, functional fertilizers can be added, and comprise monopotassium phosphate. The optimized pepper yield increasing combination comprises the following components in parts by weight: 200 portions of uniconazole, 400 portions of triacontanol, 0.5 to 2.0 portions of potassium dihydrogen phosphate.
The application method of the pepper yield increasing combination is to spray the pepper yield increasing combination added with water on the leaf surface. The application time is that the pepper yield-increasing composition is applied when the average length of pepper branches is 60-70 cm.
The invention also provides application of the pepper yield increasing combination in pepper yield increase.
