嫁接栽培是防治西红柿连作危害的适宜方法。但是嫁接育苗工作量大,采用“摘心双枝整形栽培”新技术可以减少育苗株数一半。现概要介绍如下: 一、西红柿抑制栽培的成效 黑龙江省西红柿抑制栽培在市郊钟植面积逐年扩大,保护地甜瓜面积也正在增加。甜瓜的后作种植抑制栽培西红柿是较好的轮作方式,嫁接是防治西红柿青枯病的良策。而甜瓜的采收期正值西红柿嫁接和定植期,为此,在本地郊区进行西红柿摘心双枝整形栽培法的试验,并对其育苗期的摘心节位及摘心叶龄、育苗日数、N素肥量、根部调查等进行试验研究,确立技术要求。该法的优点是:育苗数减少一半,种子、床土及劳力相应减少。育苗质量好,定 Grafting cultivation is the appropriate method of preventing and curing tomato continuous cropping. However, grafting nursery workload, the use of “topping double branch plastic cultivation” new technology can reduce the number of nursery stock half. Now summarized as follows: First, the inhibitory effect of tomato cultivation Heilongjiang tomato suppression cultivation in the suburbs of the bell planting area expanded year by year, the protection of melon area is also increasing. After planting melon to inhibit cultivation of tomatoes is a better way of rotation, grafting is a good policy to control bacterial wilt of tomatoes. The muskmelon harvest period coincided with the grafting and planting of tomato. To this end, in the local suburbs tomato topping double sticks plastic cultivation test, and its nursery of ingestion node and the number of days of topping, nursery days, N Fertilizer, root investigation and other research, establish technical requirements. The advantage of this method is that the number of nurseries is reduced by half and the corresponding reduction of seeds, beds and labor. Nursery quality, set
