Description

Durian flower forcing agent, preparation method and application Technical Field The invention belongs to the field of durian cultivation, and particularly relates to a durian flower forcing agent, a preparation method and application. Background Durian (academic name: durio zibethinus Murr) is also known as the Shaozi, musk cat fruit, belonging to the Tropical deciduous tree of the kapok family. Durian pulp is nutritious and is called as fruit king. The durian has extremely high nutritive value, can strengthen the body, strengthen the spleen and tonify qi, tonify the kidney and strengthen yang and warm the body after being eaten frequently, belongs to nourishing and beneficial fruits, has the effects of activating blood and dispelling cold and relieving menstrual pain, is particularly suitable for females suffering from dysmenorrhea, can improve the cold and cool abdomen and promote the rise of body temperature, and is an ideal tonic for people with cold physique. The durian planted in Hainan is not easy to flower or has the phenomenon of less flowers and fruits in a natural state, so that the yield of the durian is greatly influenced, and the improvement of the economic benefit of durian cultivation is seriously restricted. Therefore, the durian flower growing method solves the problem that durian flowers are not easy to come or flowers and fruits are fewer, and has important promotion effects on improving the yield of durian and improving the economic benefit of durian cultivation. Disclosure of Invention The durian flower forcing agent, the preparation method and the application provided by the invention can promote durian flower coming easily after spraying, can increase the number of flower buds, and are beneficial to the increase of durian yield. The technical scheme of the invention is realized as follows: A durian flower-forcing agent comprises prohexadione calcium, potassium phosphite, bian aminopurine, thidiazuron and ethephon. Further, the durian flower forcing agent comprises, by weight, 1-5g of prohexadione calcium, 1-5g of potassium phosphite, 1-3g of Bian aminopurine, 1-3g of thidiazuron and 0.5-1.5g of ethephon. In the durian flower forcing agent, the weight ratio of the prohexadione calcium to the potassium phosphite is 2.3:2.8. Further, the durian flower forcing agent comprises the following components in parts by weight of 2.3g of prohexadione calcium, 2.8g of potassium phosphite, 2g of Bian aminopurine, 2g of thidiazuron and 1g of ethephon. The preparation method of the durian flower forcing agent comprises the following steps: Mixing prohexadione calcium, potassium phosphite, bian aminopurine, thidiazuron and ethephon uniformly. The durian flower forcing agent is applied to shortening the appearance time of durian flower buds, improving the number of durian flower bud clusters and/or promoting durian to bloom in advance. Further, in the application, after each durian flower forcing agent is diluted by 1000 times, the durian flower forcing agent is sprayed on durian trees until the edge of each leaf is dripped. Further, in the application, the durian flower forcing agent is sprayed 1 to 2 times, once every 5 to 7 days. A durian flower forcing method, comprising the following steps: The durian flower forcing agent is adopted, and after dilution, the durian tree requiring flower forcing is subjected to foliar spray. The durian flower forcing agent is sprayed at least 30 days before flowering, diluted 1000 times and sprayed on durian trees until the edge of the leaf drops, and the durian flower forcing agent is sprayed for 1-2 times every 5-7 days.
