Early-stage pear tree seedling and watermelon interplanting method

Abstract

The invention discloses an early-stage pear tree seedling and watermelon interplanting method, and relates to the technical field of pear tree interplanting planting. The method comprises the following steps that in early spring, ditching and base fertilizer applying are conducted, deep ditches with the ditch width of 0.3 m to 0.5 m and high ridges with the ridge width of 1.4 m to 1.8 m are formed, watermelon seeds are planted in the high ridges, field planting is conducted according to the plant distance of 30 cm to 60 cm, pear tree seedlings are planted and then covered with covering soil with the thickness of 3 cm to 5cm, and the covering soil is covered with covering film, wherein the covering soil is prepared from, by weight, dry mud soil, carbendazim, bentonite, stannous pyrophosphate, pelelith, brassinolide and gibberellin; field planting is conducted on the pear tree seedlings in the spring in the same year in a single-row double-plant mode according to the plant distance of 0.6 m to 1.2 m, and meanwhile water and fertilizer management is conducted; watermelons are interplanted among pear trees every year, side branches of trunks of the pear trees in the growth period are cut back by 1 / 3 to 2 / 3, pinching is conducted for culturing crowns in the fifth year, and the watermelon interplanting starts to be stopped after the eighth year. According to the method, water and fertilizer management is better achieved, growth of tea trees and the pear trees is promoted, the survival rate is increased, and waste of fertilizer and water is reduced.

Description

Technical field: [0001] The invention relates to the technical field of interplanting pear trees, in particular to a method for interplanting early pear tree seedlings and watermelons. Background technique: [0002] Existing watermelon planting includes main planting and interplanting. Interplanting can make more effective use of land resources and improve comprehensive benefits. At present, it has been promoted throughout the country. Watermelon and pear tree interplanting can make full use of sunlight and land resources, but now Some watermelon and pear tree interplanting techniques have the following problems: the root distribution of pear trees and watermelons is quite different, and pear trees are planted in deep furrows while watermelons are planted in high ridges, but pear tree seedlings require more fertilizer and watermelon than watermelon. Less water, in the prior art, watering and fertilizing in the deep ditch. Although the pear tree has obtained sufficient fertil...

[0002] Existing watermelon planting includes main planting and interplanting. Interplanting can make more effective use of land resources and improve comprehensive benefits. At present, it has been promoted throughout the country. Interplanting watermelon and pear trees can make full use of sunlight and land resources, but now Some watermelon and pear tree interplanting techniques have the following problems: the root distribution of pear trees and watermelons is quite different, and pear trees are planted in deep furrows while watermelons are planted in high ridges, but pear tree seedlings require more fertilizer and watermelons than watermelons. Less water, in the prior art, watering and fertilizing in the deep ditch. Although the pear tree has obtained sufficient fertilizer, because the water in the deep ditch is more, it is not conducive to the growth of the pear tree, and the survival rate of the pear tree is low. , the growth rate is slow, and the watermelon does not get sufficient nutrition and water and fertilizer, so it is necessary to increase the amount of fertilization and water, which will easily cause waste of water and fertilizer, and the cost of planting will increase.
