Embodiment 1

[0032] Example 1 , Cucumbers were cultivated in autumn in a solar greenhouse. 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 matrix was placed in a tray, graf...

Embodiment 2

[0045] Example 2, Cucumbers were cultivated in the solar greenhouse in early spring. The scion variety Wolin 3 was planted on December 5 and planted on January 20 of the second year 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.

Abstract

The invention provides a method for cultivating healthy grafting seedlings of cucumbers. Turf, vermiculite and pearlite are mixed according to the volume ratio of 6:3:1 to prepare seedling cultivating substrates, teaselgourd in Africa is selected as stock, and the operation of raising seedlings by grafting in plug trays is performed; the stock is sown 5-7 days earlier than scions, and the stock is sown in 72-hole plug trays; the scions are sown in flat trays; 5-8 ml of a potassium phosphite aqueous solution with the concentration being 50 mg.kg-1 is applied to each tomato seedling from the time when the stock buds to the time when cotyledons are expanded; grafting is performed when the core of a first main leaf of the stock is exposed, the steam thickness is 2.5-3 mm, seed leaves of the scions become green, and the stem thickness is 1.5-2 mm; 8-10 ml of a prohexadione-calcium aqueous solution with the concentration being 20 mg.kg-1 is applied to each cucumber seedling when the length of a second main leaf is 1 cm after grafting; 10-12 ml of a Dufulin aqueous solution with the concentration being 100 mg.kg-1 is applied to each cucumber seedling when the length of a third main leaf is 1 cm after grafting. The grafting seedlings cultivated through the method have a remarkable preventing and treating effect on the root-knot nematode disease and virus diseases in the field.

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...
