Regulating agent capable of promoting development and fruit setting of pistillate flowers, and preparation method thereof

Abstract

The invention discloses a regulating agent capable of promoting the development and fruit setting of pistillate flowers, and a preparation method thereof. The regulating agent comprises 30 to 50% of calcium potassium nitrate, 15 to 25% of magnesium potassium nitrate, 0.1 to 1.0% of dihydrozeatin riboside, 0.1 to 0.5% of ethephon, 5 to 10% of boric acid, 1 to 2% of an emulsifier xanthan gum and 15to 50% of water. The regulating agent provided by the invention employs ethephon and dihydrozeatin riboside with promoting effects on the basis of the growth and nutrient demand characteristics of balsam pears and directed at problems occurred in the differentiation, development and fruit setting of pistillate flowers, so the regulating agent can change the sex differentiation direction of the flowers in an early development stage of the flowers and promote increase in the number of the pistillate flowers; meanwhile, the regulating agent supplements nutrients such as nitrogen, potassium, calcium, magnesium and boron needed for fruit swelling of the balsam pears so as to promote the rapid swelling of balsam pear fruit, and the purposes of eliminating abnormal balsam pears, increasing yieldand improving quality are achieved.

Description

Technical field [0001] The invention relates to the technical field of balsam pear growth regulators, in particular to a regulator for promoting the development of female flowers and fruit setting of balsam pear and a preparation method thereof. Background technique [0002] The common problems in summer balsam pear planting are fewer female flowers and low fruit setting rate, which leads to low yield. The main reasons for this problem are as follows: [0003] First, because the flower bud differentiation of balsam pear starts from the seedling stage, the environmental conditions at the seedling stage have a greater impact on the amount of female flower differentiation, resulting in a relatively high amount of female flower differentiation. Temperatures below 20°C and short days (less than 12 hours) are conducive to the development of bitter melon female flowers, but it is difficult to do both in summer seedlings. Vegetable farmers’ experience is to choose a place with shade in t...

AI Technical Summary

Problems solved by technology

[0005] Based on the above situation, in order to improve the female flower differentiation rate and fruit setting rate of bitter melon cultivation, growth hormones such as ethephon, indole acetic acid, and gibberellin, which are commonly used in bitter melon cultivation, can regulate the growth of bitter melon, but the regulation of the above growth hormones Phytochemicals can only promote differentiation and fruiting, but cannot effectively improve the growth quality of fruits, and tend to produce more low-quality fruits (such as deformed melons); and the dosage and time of these hormones are more difficult to control, and it is easier to remain in the fruit
