An inducer for pumpkin growth regulation and its application method

Abstract

The invention provides an inductive agent for pumpkin growth regulation. The inductive agent comprises, by weight, 6.5-8.5 parts of mepiquat chloride, 5.0-7.5 parts of ethephon and the balance of water. The mepiquat chloride in the inductive agent can effectively shorten extension length of melon vines, seedling conserving per mu is increased, land utilization rate is increased, plant photosynthetic capacity is enhanced, and fruit setting rate is increased; the ethephon has inductive regulation function on male and female flowers of pumpkins, male flowers are enabled not to basically appear in pollination period of the pumpkins, 5-8 female flowers appear continuously, flowering period is concentrated, pollination period is effectively shortened, and labor cost is reduced; pumpkin seedlings are treated in different time periods with the inductive agent different in concentration, mature consistency of seeds can be effectively increased, seed quality is improved, and seed production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of pumpkin cultivation, in particular to an inducer for regulating the growth of male and female flowers of pumpkins, reducing the occurrence probability of male flowers, increasing the number of female flowers, and regulating the internode length of melon vines and an application method thereof. Background technique [0002] Pumpkin, also known as pumpkin, red gourd, rice melon, etc., is native to Central and South America and is an annual vine herb. Pumpkin is rich in nutrition and has medical and health effects. It is recognized as a health-care melon vegetable worldwide. It is popular among consumers and its cultivation area is expanding year by year. The seeds currently used in production are mainly hybrids. [0003] Pumpkin hybrid seed production generally adopts open-field water and dry pond mulching cultivation. Many hybrid varieties use wild pumpkins as their male parents, which have a smaller plant...

AI Technical Summary

Problems solved by technology

During hybrid seed production, for the convenience of hybrid pollination, the width of each pond is generally 3.5-4 meters, and the number of seedlings per mu is only about 1,000, which seriously affects the increase in yield and benefit of pumpkin hybrid seed production, and also greatly reduces land use. Rate

In addition, pumpkin is a monoecious crop. During the hybrid pollination period, the probability of female flowers appearing is only 1 / 3-1 / 5 of that of male flowers. There are more male flowers and fewer female flowers. The pollination time is not concentrated, the pollination cycle is long, and the flower cleaning work is greatly increased. labor input cost

[0004] In order to solve the above problems, the combined pumpkin growth regulation inducer is used to induce and regulate the growth of the male and female flowers of pumpkin and the length of the internodes of the melon vines, which solves the problem of some inducers suitable for pumpkin cultivation in the current pumpkin cultivation. Although the growth of pumpkin can be adjusted after treatment, due to the influence of the single use of the medicine or the concentration of the combined medicine solution, the seed maturity and consistency are poor, the quality is not high, the ability to increase the yield is limited, and the expected effect cannot be achieved. , which affects the output-to-investment ratio of seed producers and restricts the development of the pumpkin industry
