Period production method for adjusting pineapple production period

Abstract

The invention discloses a period production method for adjusting the pineapple production period, and belongs to the field of plant cultivation. The method comprises the following steps of soil preparation and ridging, selection of seedlings, field planting, fertilizing management, induced flower forcing, bud removing, bud leaving and flower and fruit management. Aiming at different pineapple economic cultivation varieties, the seedlings different in planting time and specification are scientifically selected, and the influence of natural flower formation on the number of flower forcing plants can be effectively avoided or reduced; meanwhile, by reinforcing the measures such as fertilization management, induced flower forcing and flower and fruit management, spring planting in March and April in the current year is achieved; induced flower forcing is carried out in September and October of the current year, fruits are harvested in April and May of the next year, seedlings are harvested in August and September in the next year, and the seedlings can be used for autumn planting and production; or autumn planting is carried out in August and September in the current year, flower forcing is carried out in April and May in the next year, fruits are harvested in September and October of the next year, the seedlings are harvested in March and April in the year after next, and the seedlings can be used for spring planting and production.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a periodic production method for regulating the production period of pineapple. Background technique [0002] Pineapple (Ananas comosus (L) Merr.), also known as pineapple, is a herbaceous plant of Bromeliaceae and the genus Ananas. Its position in tropical fruit production and trade is second only to bananas and mangoes. It is an important crop in Central and South America and the Asia-Pacific region. One of the economic crops. my country is a big pineapple producing country in the world, and the total pineapple planting area in the country is expanding year by year. However, the fresh pineapples in my country's main pineapple producing areas such as Guangdong, Hainan, and Taiwan are still concentrated in winter and spring (January-March) when the fruit quality is not good. In the summer (July-August) when tropical bulk fruits are concentrated and ripe, fresh fruits ...

AI Technical Summary

Problems solved by technology

[0004] Because the pineapples planted in Guangxi are induced by low temperature and short sunshine in winter, pineapples tend to flower naturally during this period, and different varieties of pineapples show different natural flowering rates. "Philippines" and "Philippines" pineapples have a natural flowering rate of less than 30%, but the new varieties "Golden Pineapple" and "Tainong 21" have a higher natural flowering rate than other varieties, especially in the weather affected by low temperature and frost in winter. The natural flowering rate can be as high as more than 80%. The fruit is small and the commodity rate is low, which not only reduces the overall output value, but also seriously disrupts the planting production plan. The seedling supply and production cycle of the best varieties are not connected, and the effect of improving the quality and efficiency of the production period adjustment technology of new varieties has not been reflected. Therefore, the enthusiasm of the growers for production is not high, which seriously affects the sustainable development of the industry.
