Embodiment 1

[0024] When the number of leaves of the pineapple plant reaches 30-35 leaves, the calcium carbide solution is artificially poured into the pineapple flower center to promote flowering. Accurately weigh 375g of calcium carbide, put it into a special powder sprayer filled with 15L of water for calcium carbide, let it stand for 5 minutes, and fill the pineapple flower heart with 15ml / plant; 2 days later, follow the above operation to pour the heart again. After 30 days, all the pineapples bloomed, the flowering rate reached 100%, and the flowering regularity was more than 80% (the natural flowering rate of pineapples without calcium carbide solution was about 10-20%).

Embodiment 2

[0026] When the number of leaves of the pineapple plant reaches 30-35 leaves, the calcium carbide solution is artificially poured into the pineapple flower center to promote flowering. Accurately weigh 400g of calcium carbide, put it into a special spraying bucket filled with 20L of water for calcium carbide, and after standing for 6 minutes, fill the pineapple flower heart with 12ml / plant; after 3 days, follow the above operation to pour the heart again. After 40 days, the pineapple flowering rate reached 90%, and the flowering uniformity was above 80%.

Embodiment 3

[0028] When the number of leaves of the pineapple plant reaches 30-35 leaves, the calcium carbide solution is artificially poured into the pineapple flower center to promote flowering. Accurately weigh 540kg of calcium carbide, put it into a special spraying bucket filled with 18L of water for calcium carbide, and after standing for 5 minutes, fill the pineapple flower heart with 15ml / plant; 2 days later, follow the above operation to pour the heart again. After 30 days, the pineapple flowering rate reached 100%, and the flowering uniformity was above 80%.

[0029] As can be seen from the above examples, the present invention can significantly improve the flowering rate and flowering regularity of pineapple.

Abstract

The invention belongs to the technical field of pineapple flower forcing, and provides application of a calcium carbide solution in improving the flowering rate and flowering uniformity of pineapples, the concentration of the calcium carbide solution is 20-30 g / L. The flowering rate and flowering uniformity of pineapple plants are remarkably improved by filling pineapple flower hearts with the calcium carbide solution with the concentration.

Description

technical field [0001] The invention relates to the technical field of pineapple flower promotion, in particular to the application of a calcium carbide solution in improving pineapple flowering rate and flowering uniformity. Background technique [0002] In pineapple production, the natural flowering rate is low and irregular, resulting in different fruit sizes and uneven harvesting periods, seriously affecting market sales. In order to improve the economic benefits of commercial fruit and realize the annual fruit supply, pineapple mainly relies on mechanical force flowering at present. Although mechanical flower urging has high efficiency and large dosage (150ml / plant), the flower urging effect is poor. Therefore, up to the present, do not yet obtain a kind of pineapple flower prompting method that the rate of flower formation is high and the uniformity of flowering is good. Contents of the invention [0003] The purpose of the invention is to solve the problems of low...
