Towel gourd fruit setting pollination agent capable of preventing gray mold

Abstract

The invention discloses a towel gourd fruit setting pollination agent capable of preventing gray mold. The agent comprises 10 parts of 0.1% forchlorfenuron, 1.25-2 parts of 25g / L fludioxonil and 1000 parts of water. The ingredients are evenly stirred and used, wherein the useful life can not go beyond 6 hours, and the pollination temperature is 15-40DEG C. According to the towel gourd fruit setting pollination agent provided by the invention, after the scientific chemical agent is used, the pollination process is less influenced by the external environment, the pollination work can be carried out under the low-temperature scant lighting special environment, and the occurrence rate of the gray mold can be controlled to be less than 1%. After the method is used, the pollination time interval of the towel gourd can be prolonged, and the towel gourd fruit setting pollination agent has the characteristics of being work-saving and labor-saving, so that the produced towel gourd has the advantages of being free from towel gourd disappearance, quick in fruit expansion, and less in seeds, the percentage of the fertile fruit of the pollinated towel gourd can be more than 98%, and the percentage of the high-quality towel gourd number to the total towel gourd number is more than 98%.

Description

technical field [0001] The invention relates to a loofah fruit setting pollination agent capable of preventing botrytis cinerea. Background technique [0002] Loofah is an annual climbing vine, dioecious, resistant to high temperature and humidity, and avoids low temperature. Because it contains more nutrients than melons, loofah has become one of the most popular vegetables. At present, the traditional pollination method for loofah fruit setting is to wait for the male flower to open to produce pollen, and then pollen the produced pollen to the pistil stigma. Since the female flower of loofah is open from evening to early morning of the next day, and in a special environment with low temperature and little sunshine, the male flower It is not easy to produce pollen, and the above-mentioned influencing factors all seriously limit the pollination operation of loofah, which brings great inconvenience to the melon farmers.

[0003] Forchlorfenuron, chemical name 1-(2-chloro-pyridine)-3-phenylurea, is a novel plant growth regulator widely used in recent years. At present, forchlorfenuron has been widely used in pollination of Hami melon in Hainan, Preliminary research results have found that 0.1% forchlorfenuron can promote loofah fruit setting by 100 times, but in the special environment of low temperature and low light, loofah after pollination is very prone to gray mold, resulting in a decline in loofah fruit setting rate
