Planting management method of high-yield large-fruit type ponkan

Abstract

The invention provides a planting management method of high-yield large-fruit type ponkan. The method specifically comprises the following steps of: 1, selecting an appropriate cultivation field and preparing the field; 2, managing: S1, ditching and applying an organic-inorganic compound fertilizer once before sprouting in spring; S2, spraying ethephon in a first physiological blossom drop period;S3, spraying 2, 4-DP in a second physiological fruit drop period; S4, ditching and applying the organic-inorganic compound fertilizer once after the end of the second physiological fruit drop period;and S3, preventing and controlling diseases and insects. The planting method can improve the yield per unit area of a citrus orchard, the yield per unit volume measured and calculated by the method is as high as 4383.24-4912.16 g / 0.125m<3>, the total yield per cubic volume of the crown is 34-40 kg, and the transverse diameter of fruit is bigger than 80 mm.

Description

technical field [0001] The invention relates to the technical field of production management of high-yield orchards, in particular to a method for planting and managing high-yield large-fruit ponkans. Background technique [0002] Ponkan, also known as citrus, is easy to peel off, the flesh is crisp, tender, sweet and fragrant, juicy and slag-like, and has aroma. It is one of the varieties with the best fresh food quality among wide-skinned citrus. Ponkans with a transverse diameter greater than 70 mm performed the best in terms of appearance and internal quality, were generally favored by consumers, and had the highest price. Artificial flower thinning and fruit thinning in the production process is the main way to produce large fruits, but it is laborious and laborious, and greatly increases the production cost. Statistics have found that if two rounds of flower thinning and fruit thinning are completed, the labor input cost for flower thinning and fruit thinning is calcu...

Problems solved by technology

Artificial flower thinning and fruit thinning in the production process is the main way to produce large fruits, but it is labor-intensive and greatly increases the production cost

Statistics have found that if two rounds of flower thinning and fruit thinning are completed, the labor input cost for flower thinning and fruit thinning is calculated at 80 yuan per person per day per 667m 2 Add at least 240 yuan

The substantial increase in production costs will inevitably lead to a decline in the economic benefits of production, thereby restricting the healthy development of the ponkan industry

[0003] Aiming at the labor-intensive and labor-intensive artificial flower and fruit thinning and the increase in planting costs, to a certain extent, it is no longer suitable for the current production situation of labor shortage and greatly increased labor costs. technology

However, there are almost no reports on the production of citrus, especially ponkan
