Problems solved by technology

[0003] Since the pineapple flower can be directly observed after the flowering, the middle core leaves are red and the flower core is visible, the flower bud differentiation period has passed, and the best time for top dressing has been missed, resulting in problems such as underdevelopment of the fruit neck and tower-shaped fruit.

Embodiment 1

[0030] The pineapple variety Tainong No. 16 (Sweet Honey) that was forced to flower in early October 2016 was selected, and the second or third smallest core leaf that can be seen by the naked eye in the core nest of the plant was extracted the next day from the first ten days to the middle of November 2016. , Observe the shrinkage and discoloration of the base of the core leaf. In mid-November, the base of the core leaf is lantern-shaped, the base is smaller than the middle, the diameter of the base is 3-6 cm, the middle is 5-10 cm from the base, the midrib of the leaf is dark red, and the base is warped when the leaf is laid flat from 30-45° angle, such as image 3 As shown in the leaf A in the figure, it was determined that the plant had entered the flower bud differentiation stage. Then fill the core with 100ml per plant, which is composed of 17 parts of fruit moistening 300 times, 18 parts of Megafur 450 times, 8 parts of potassium chloride, 7 parts of potassium sulfate,...

Embodiment 2

[0034] The pineapple variety Tainong No. 4 (hand-sheared pineapple) that was forced to flower in mid-April 2017 was selected, and the second or third smallest core leaf that can be seen by the naked eye in the core nest of the plant was extracted the next day in early May 2017. Observe the shrinkage and discoloration of the core leaf base. In the first ten days of May, the base of the core leaf is lantern-shaped, the base is smaller than the middle, the diameter of the base is 3-6 cm, the middle is 5-10 cm from the base, the midrib of the leaf is dark red, and the base is warped when the leaf is laid flat From the angle of 30-45°, it is determined that the plant has entered the flower bud differentiation stage. Then fill the core of each plant with 105ml, which is composed of 15 parts of fruit moisturizing 300 times, 15 parts of Megafur 400 times, 7 parts of potassium chloride, 8 parts of potassium sulfate, 11 parts of superphosphate, 9 parts of urea and 4 parts of yeast selen...

Embodiment 3

[0037] The pineapple variety Tainong No. 16 (Sweet Honey) that was forced to flower in early May 2017 was selected, and the second or third smallest core leaf that can be seen by the naked eye in the core nest of the plant was extracted the next day from mid to late May 2017 , Observe the shrinkage and discoloration of the base of the core leaf. In late May, the base of the core leaf is lantern-shaped, the base is smaller than the middle, the diameter of the base is 3-6 cm, the middle is 5-10 cm from the base, the midrib of the leaf is dark red, and the base is warped when the leaf is laid flat From the angle of 30-45°, it is determined that the plant has entered the flower bud differentiation stage. Then fill the core of each plant with 100ml, which is composed of 12 parts of fruit moisturizing 300 times, 13 parts of Megafu 450 times, 9 parts of potassium chloride, 6 parts of potassium sulfate, 10 parts of superphosphate, 8 parts of urea and 3.5 parts of yeast selenium. Fert...

Abstract

The invention discloses a method for improving a pineapple fruit shape and belongs to the technical field of plant cultivation. According to the method, after pineapple plant flowering forcing, core leaves are periodically extracted, a flower bud differentiation period is determined by observing the shrinkage discoloration condition of the base parts of the core leaves, and a core fruit fertilizeris irrigated in time after the flower bud differentiation period is determined so that undeveloped fruits on the necks of pineapples and the appearance of tower-shaped fruits can be effectively prevented. The proportion of normally cultivated tower-shaped fruits and anti-season tower-shaped fruits of a fresh pineapple variety cultivated by the method can be reduced to 1% or below, the proportionof undeveloped single fruits can be reduced to 5% or below, the fruit shape of the pineapples can be effectively improved, and the commodity fruit rate and the quality yield of the fresh pineapples are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to the technical field of fresh pineapple cultivation, in particular to a method for improving the fruit shape of pineapple. Background technique [0002] With the improvement of domestic living standards, the demand for imported characteristic fruits is also increasing. Pineapple, as a characteristic fresh pineapple variety different from the traditional domestic Balinese pineapple, is more and more popular in the domestic market. At present, Guangdong, Hainan, Guangxi and other places have begun to Large-scale experimental planting. Because there are many varieties of pineapples, the characteristics of the varieties are obviously different, and the phenology is seriously different, so different management methods are required. At present, the domestically introduced pineapple varieties Tainong No. 16 (Sweet Honey) and Tainong No. 4 (hand-sheared pineapple) have serious ...
