Abstract
The invention belongs to the technical field of pineapple flower forcing, and provides application of a calcium carbide solution in improving pineapple flower forming rate and flowering uniformity, wherein the concentration of the calcium carbide solution is 20-30 g/L, and pineapple flower cores are irrigated by the calcium carbide solution with the concentration, so that the flowering rate and the flowering uniformity of pineapple plants are obviously improved.
Description
Technical Field
The invention relates to the technical field of pineapple flower forcing, in particular to application of a calcium carbide solution in improving pineapple flower forming rate and flowering uniformity.
Background
In pineapple production, natural flowering rate is low, and fruits are not uniform in size and are not concentrated in harvest period due to irregular, so that market sales are seriously affected. In order to improve the economic benefit of commodity fruits and realize annual fruit supply, pineapple is mainly subjected to mechanical flower forcing at present. The mechanical flower forcing effect is poor although the efficiency is high and the dosage is large (150 ml/plant). Thus, a pineapple flower forcing method with high flower forming rate and good flowering uniformity has not been obtained so far.
Disclosure of Invention
The invention aims to solve the problems of low flowering rate and poor flowering uniformity of pineapple plants.
In order to achieve the above object, the present invention provides the following technical solutions:
the invention provides application of a calcium carbide solution in improving pineapple flower forming rate and flowering uniformity, wherein the concentration of the calcium carbide solution is 20-30 g/L.
The invention also provides a method for promoting the flowering rate and the flowering uniformity of the pineapple by using the calcium carbide solution, wherein the pineapple flower center is irrigated with the calcium carbide solution for promoting the flowering, and the concentration of the calcium carbide solution is 20-30 g/l.
Preferably, the dosage of the calcium carbide solution is 10-20 ml/strain.
Preferably, the calcium carbide solution is prepared 4-6 min before use.
Preferably, the pineapple flower core filling time is when pineapple plants grow to 30-35 leaves.
Preferably, the number of times of pineapple flower hearts is 2-3; the time interval for each pineapple flower core filling is 2-3 days
The calcium carbide described in the present invention is also called calcium carbide (CaC) 2 ) The calcium carbide is dissolved in water and reacts with the water to generate acetylene, and the acetylene has a flower forcing effect. The invention improves the pineapple flower forming rate and the flowering uniformity by quantifying the concentration and the consumption of the calcium carbide solution, the harvesting period is concentrated, the economic benefit of commodity fruits is improved, and the annual fruit supply is realized.
Detailed Description
The invention provides application of a calcium carbide solution in improving pineapple flower forming rate and flowering uniformity, wherein the concentration of the calcium carbide solution is 20-30 g/L.
In the present invention, the concentration of the calcium carbide solution is preferably 20 to 30g/L, more preferably 20g/L, 21g/L, 22g/L, 23g/L, 24g/L, 25g/L, 26g/L, 27g/L, 28g/L, 29g/L, 30g/L, and still more preferably 25g/L.
The invention also provides a method for promoting the flowering rate and the flowering uniformity of the pineapple by using the calcium carbide solution, wherein the pineapple flower center is irrigated with the calcium carbide solution for promoting the flowering, and the concentration of the calcium carbide solution is 20-30 g/l.
In the present invention, the concentration of the calcium carbide solution is preferably 20 to 30g/L, more preferably 20g/L, 21g/L, 22g/L, 23g/L, 24g/L, 25g/L, 26g/L, 27g/L, 28g/L, 29g/L, 30g/L, and still more preferably 25g/L.
In the summary of the present invention, the amount of the calcium carbide solution is preferably 10 to 20 ml/strain, more preferably 12 to 18 ml/strain, still more preferably 15 ml/strain.
In the present invention, the calcium carbide solution is preferably disposed 4 to 6 minutes before use, and more preferably disposed 5 minutes before use.
In the invention, the timing of the pineapple flower heart irrigation is preferably when pineapple plants grow to 30-35 leaves.
In the present invention, the number of times of the pineapple flower core is preferably 2 to 3 times, more preferably 2 times.
In the present invention, the time interval for each pineapple flower core irrigation is preferably 2 to 3 days, more preferably 2 days.
In the invention, the pineapple flower heart is preferably carried out on a cloudy day or in the evening.
The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.
Example 1
And when the number of the leaves of the pineapple plant reaches 30-35 leaves, manually pouring the calcium carbide solution into the pineapple flower heart to promote the flower. Precisely weighing 375g of calcium carbide, putting the calcium carbide into a special calcium carbide laxative barrel filled with 15L of water, standing for 5min, and filling pineapple flower cores according to 15 ml/plant; after 2 days, the core was refilled once according to the above procedure. After 30 days, the pineapple flowers completely, the flowering rate reaches 100%, and the flowering uniformity is over 80% (the natural flowering rate of the pineapple which is not catalyzed by the calcium carbide solution is about 10-20%).
Example 2
And when the number of the leaves of the pineapple plant reaches 30-35 leaves, manually pouring the calcium carbide solution into the pineapple flower heart to promote the flower. Accurately weighing 400g of calcium carbide, putting the calcium carbide into a special calcium carbide laxative barrel filled with 20L of water, standing for 6min, and filling pineapple flower cores according to 12 ml/plant; after 3 days, the core was refilled once according to the above procedure. After 40 days, the pineapple flowering rate reaches 90%, and the flowering uniformity is more than 80%.
Example 3
And when the number of the leaves of the pineapple plant reaches 30-35 leaves, manually pouring the calcium carbide solution into the pineapple flower heart to promote the flower. Accurately weighing 540kg of calcium carbide, putting the calcium carbide into a special calcium carbide laxative barrel filled with 18L of water, standing for 5min, and filling pineapple flower cores according to 15 ml/plant; after 2 days, the core was refilled once according to the above procedure. After 30 days, the pineapple flowering rate reaches 100%, and the flowering uniformity is more than 80%.
From the above examples, the present invention can significantly improve the flowering rate and the flowering uniformity of pineapple.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
