Description
Technical Field
The invention relates to a plant growth regulator, in particular to a litchi flower-protecting fruit-setting regulator and a preparation and application method thereof.
Background
Litchi is a common subtropical fruit, the peel of the litchi is bright red, the pulp is white and crystal clear, the juice is rich and sweet, the litchi is generally flowering in 3-4 months every year, the fruits are mature successively in 5-8 months, and the flowering and fruiting time of different litchi trees is slightly different. The growth of litchi tree is especially sensitive to weather and climate change, and the temperature and weather are good and bad, so that the growth, flowering and fruiting of litchi tree can be directly affected. When the air temperature is higher, litchi trees are only grown in the flowering period and are difficult to flower, and the phenomenon that flowers and leaves are changed easily occurs after the flowers are formed, if the flowers are subjected to high-temperature weather for more than 3 days after the flowers are formed, the phenomenon of flowers burning occurs, and if the fruits are continuously high-temperature and suddenly rained in the young fruit period, the fruits are seriously damaged; when the air temperature is low, litchi trees can not form flowers in the flowering period, are easily frozen out and killed after the flowers are formed, and are difficult to pollinate and fruit after the flowers are opened. As the comprehensive flowering time of the litchi tree is only about 10 days in sunny days, if long-time raining is encountered during flowering, continuous retting for 5-20 days or more can lead to the phenomena that retting necrotic flowers and flowering cannot pollinate or pollinate insufficiently, and the fruit setting rate is seriously affected.
Because flowering and fruiting of litchi trees are greatly affected by weather and climate, and weather corresponding to flowering, flowering and fruiting periods of litchi trees is often uncertain every year, the harvesting of litchi trees is often divided into years, and when weather and climate are poor in the year, the harvesting of litchi trees is suddenly reduced, so that loss of fruit farmers is large.
Disclosure of Invention
The invention aims to provide a litchi flower-protecting fruit-setting regulator for litchi fruit farmers, and the regulator is used for carrying out artificial interference on the growth stage before the litchi flowers fully, so that the litchi flowers are not changed into flowers, the flowers are protected, the fruit setting rate is improved, the influence of various weather and climate on the long leaves, the flowers and the fruits of the litchi is overcome, and the great harvest of the litchi fruit farmers can be ensured.

3. Actual use effect comparison
The effect of the regulator prepared in the above examples 1 to 3 was compared with that of litchi tree without the regulator of the present invention when used in Guangxi-Gui flat market where the present inventors are located as follows:
The litchi harvesting yield per year after the litchi tree flower-protecting fruit-setting regulator is used in recent years by the inventor is listed as follows:
From the above table, it can be seen that the yields of litchi remain relatively high and stable regardless of weather and climate for the remaining years, except that the weather and climate for the individual years are particularly good, resulting in an explosion in litchi yield.
4. Process of the invention
The inventor utilizes the local temperate climate of Guangxi-flat market, can plant litchi and develop the natural condition advantage of litchi production, since 1983, inputs a great deal of manpower and material resources to carry out scientific management research on litchi production, successfully develops a preservative for the non-picked litchi on the tree and obtains the national invention patent (CN 201019179003.5) after a plurality of years of diligent research and development, and can delay the ripening and preservation of the litchi by applying the preservative to the litchi tree, so that the ripe litchi can prolong the harvest time, and the preservative is not only the preservative for fruits on the tree but also the regulator for the fruit growth process on the tree. However, the preservative is used after the litchi tree flowers and fruits are formed, and the fruit setting rate of the litchi tree cannot be obviously improved. In the process of fruiting of the litchi tree, the effect of weather and climate is great, when severe weather and climate are encountered in the flowering period, a series of phenomena such as flower leaf changing, drought and flower burning, flower retting and death, plant diseases and insect damage, insufficient flowering and pollination and the like are caused, the fruiting rate is seriously influenced, and the fruiting rate of the litchi tree is finally reduced, so that the fruiting of the litchi tree is reduced. Therefore, the inventor further explores practice and experiments, is hard to develop, and finally successfully develops the litchi flower-preserving fruit setting regulator applied before the litchi flowers fully bloom, which is applied to the litchi according to different growth stages before the litchi flowers fully bloom, can promote the growth of flowers in the season of flowers, overcomes the influence of any bad weather and climate on the flowers, ensures high and stable fruit setting rate, ensures that the litchi fruits can be harvested greatly without being separated from the size of the year, and the harvested litchi has beautiful color and good quality.
For many years, besides being used on litchi trees planted by the inventor, the regulator is popularized to part of fruit growers and relatives and friends in 2007, such as: tin planting sources of Mafield officers towards villages, He Yutian of He Village, Liang Yaoshan of Liang Village, Huang Xinglian and Huang Yuanlian of Shanggu, Chen Yongchong of Chen Village, Chen Bangyi of Mupeng Village, Lu Xianzhao of Baishi Village and the like, which can be used for all times as required, the litchi tree can still have flowers from no flowers to flowers even in the weather and the severe weather, flowers are preserved, fruits are more, the harvested fruits are bright red in color, uniform in size, free of diseases, free of insects and cracks, and very satisfactory in effect. Later in 2008, the inventor disclosed and promoted the regulator to be used by more fruit growers in Guangxi flat market Ma Zhen, and after the regulator is used, the regulator has good universal reflection effect, and a plurality of successful stories are developed and written into a manuscript spontaneously for propaganda, such as: dan Jiang, huang Jinhua, zhi Shu, mi Dan, liang Cun, liang Yaoshan, xian Zhi Yi, have already used the regulator of the present invention for tens of thousands of fruit growers at present, and the effect is remarkable.
