Jackfruit tree pollen solution, preparation method thereof and hand pollination method

Abstract

The invention relates to a jackfruit tree pollen solution and a preparation method and application thereof. The pollen solution is prepared from sucrose, anhydrous calcium chloride, boric acid, waterand male inflorescence. When the jackfruit tree pollen solution is used for hand pollination, the pollen solution prepared on the same day is poured into a sprayer, and is sprayed onto female inflorescence showing on stigma at 8-10am or 4-6pm and is sprayed again the next day. The pollen solution can improve the pollen germination rate and stigma receptivity; in preparation of the pollen solution,a vortex washing method is adopted due to small but sticky jackfruit pollen particles, and the method can collect enough jackfruit pollen particles. When being used for hand pollination, the jackfruit tree pollen solution can prevent malformed jackfruits effectively, and the commercial fruit rate reaches up to 95% or more.

Description

technical field [0001] The invention relates to a jackfruit fruit tree cultivation technique, in particular to a jackfruit fruit tree pollen liquid and a pollination method thereof for reducing the probability of deformed jackfruit fruit. Background technique [0002] Jackfruit, also known as tree pineapple, jackfruit, and tripe fruit, is a plant of the genus Jackfruit in the family Moraceae. It is a rare fruit in the tropics and south subtropics of my country. Its fruit is large and fragrant, the flesh is crisp and sweet (dry bud), and its flavor is unique, so it is very popular among consumers. In addition to being eaten fresh, the fruit can also be used for cooking, drying or making preserves; the seeds can be used as woody food; the plants are resistant to barrenness, extensive management, early results, high yield, and have very broad industrialization prospects. The planting area in places such as China, Guangxi and Hainan continues to expand. [0003] With the conti...

Problems solved by technology

Some jackfruit plants have almost no normal fruit shape, which seriously affects the commercial fruit rate and economic benefits of jackfruit plantations

[0004] After continuous exploration, the inventor found that the main reason for the abnormal fruit of jackfruit is that the pollination and fertilization are uneven and incomplete.

[0005] Existing artificial pollination technology for fruit trees mainly adopts natural drying to collect pollen, rubber tip flowers, etc., but the pollen grains of jackfruit are very small, and the pollen grains are bonded to each other, so it is difficult to collect with the existing technology; in addition, the germination rate of jackfruit pollen is low, and the room temperature quickly lose vitality
