Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for cultivating healthy cucumber grafted seedlings for the above problems, which overcomes the fact that the prior art cannot effectively reduce root-knot nematodes and viral diseases, easily cause grafted seedlings to grow excessively, the quality of grafted seedlings declines, and the yield is low However, after adopting the method of the present invention, the occurrence of difficult diseases such as root-knot nematodes and viral diseases can be effectively prevented, the use of chemical pesticides can be reduced, and at the same time, it is beneficial to cultivate strong seedlings, promote good differentiation of flower buds, and achieve high and stable yields of cucumbers

Embodiment 1

[0032] Example 1. Cucumbers were cultivated in a solar greenhouse with delayed cropping in autumn. The scion variety planted was Xinjin No. 11. It was sown on July 1 and planted on August 5. The location was in a vegetable greenhouse in Shouguang, Shandong. Set up 2 treatments without using any chemical pesticides to control root-knot nematodes and viral diseases. Except for the required measures, other management measures are exactly the same.

[0033] Process 1: Adopt the method of the present invention to cultivate grafted seedlings

[0034] Mix peat, vermiculite, and perlite uniformly in a volume ratio of 6:3:1, and at the same time add an appropriate amount of fully soluble all-element compound fertilizer to prepare a seedling substrate, so that the initial nutrients of the seedling substrate N, P 2 o 5 、K 2 O content: 60-80mg·kg -1 , 20-40mg·kg -1 , 50-100mg·kg -1 , appropriate amount of medium and trace elements, EC value 1.0-1.5ms·cm -1 , after the substrate was ...

Embodiment 2

[0045] Example 2: Cucumbers were cultivated in early spring in a solar greenhouse. The scion variety Wolin 3 was planted. It was sown on December 5 and planted on January 20 of the second year. The location was in a vegetable greenhouse in Shouguang, Shandong. Set up 2 treatments without using any chemical pesticides to control root-knot nematodes and viral diseases. Except for the required measures, other management measures are exactly the same.

[0046] Process 1: Adopt the method of the present invention to cultivate grafted seedlings

Abstract

The invention provides a method for cultivating healthy cucumber grafted seedlings. Peat, vermiculite, and perlite are mixed with a seedling-raising substrate according to a volume ratio of 6:3:1, and African sting melon is selected as a rootstock to carry out plug-in tray grafting and seedling cultivation; the ratio of rootstock to scion is 5-7 days early sowing, the rootstock is sown on a 72-hole hole tray; the scion is sown on a flat tray; when the rootstock sprouts and the cotyledons unfold, each plant is poured with 5-8ml of 50mg·kg-1 potassium phosphite aqueous solution; the first true leaf of the rootstock is exposed , stem diameter 2.5‑3mm, scion cotyledons turn green, graft when stem diameter is 1.5‑2mm; when the length of the second true leaf of scion reaches 1cm after grafting, each plant is poured 20mg·kg‑1 calcium prohexadione aqueous solution 8‑ 10ml; when the 3rd true leaf length of the scion reaches 1cm after grafting, every plant pours 10-12ml of the parafluorophos aqueous solution of 100mg kg-1, and the grafted seedlings bred by the present invention are to root-knot nematode and virus disease in the field There is a significant control effect.

Description

technical field [0001] The invention relates to a method for cultivating cucumber seedlings, in particular to a method for cultivating healthy grafted cucumber seedlings, which belongs to the technical field of vegetable seedling cultivation. Background technique [0002] Cucumber is the main variety of vegetable production in protected areas. Due to the continuous cropping cultivation for many years, the occurrence of root-knot nematode and virus disease has been increasing year by year. Root-knot nematode and virus disease have become devastating diseases of vegetable protected cultivation, often causing Severe production cuts or even no harvests. Simultaneously, traditional cucumber plug-in tray grafting seedling raising technology often easily causes grafted seedling leggy due to factors such as plug-in tray seedling-raising environment, causes grafted seedling quality to decline. [0003] At present, there is no specific agent for the control of difficult diseases such...
