Direct-seeding continuous cultivation method for lianas vegetables in greenhouse

Abstract

The invention relates to a continuous farming method of the direct sown seedlings of vine vegetables; the method is carried out in a green house; the temperature of the greenhouse is 13 DEG C to 30 DEG C, the humidity is 60 percent to 85 percent and the light time is no fewer than 8h every day; the cultured rootstock seedlings are planted at the transposition points in advance; after the seedlings grow into strong seedlings, 30cm to 50cm young vine sprouts are selected as grafts; a cutting blade is used to chamfercut from down to top between two sections of every graft, and the depth is 1.5cm to 2.5cm and the depth is no less than half of the diameter of the young sprouts; the cutting blade is used to cut both sides in the middle of the leaves in the second section of the rootstock seedling into sharp wedge shape, and the length is consistent with the notch depth of the grafts; then the two sides are butted and bound with the grafts; one month after the cut is healed, the binding is untied; old vines are cut off from below the grafting cut, pulled up together with old roots and removed outside the greenhouse; the old vines are pulled up after being cut off, plant residue is picked out to receive disinfection, and then organic fertilizer is added in. The seedling grafted through the method has high survival rate, high yield and can realize continuous production.

Description

technical field [0001] The invention relates to a method for cultivating vine vegetables, in particular to a method for continuously cultivating live seedlings of vine vegetables in a greenhouse. Background technique [0002] The cultivation of vine vegetables in greenhouses generally adopts seedling cultivation and soilless cultivation, or grafting cultivation. When the vines grow, bloom, and bear fruit in the late stage, and the length reaches more than 10 meters, if they continue to be cultivated, they can only fall to the ground. , which not only seriously occupies the surface space, but also easily breeds diseases and insect pests. At the same time, the roots and vines age and grow further. Because the transporting tissue is too long, it is difficult to fully supply nutrients to the new shoots, which in turn affects the yield and quality of the fruit. Pull out the vines.

[0002] The cultivation of vine vegetables in greenhouses generally adopts seedling cultivation and soilless cultivation, or grafting cultivation. When the vines grow, bloom, and bear fruit in the late stage, and the length reaches more than 10 meters, if they continue to be cultivated, they can only fall to the ground. , which not only seriously occupies the surface space, but also easily breeds diseases and insect pests. At the same time, the roots and vines age and grow further. Because the transporting tissue is too long, it is difficult to fully supply nutrients to the new growth, which in turn affects the yield and quality of the fruit. uproot vines

[0003] If the next production and cultivation of the same vine vegetable is carried out, it is necessary to sow seedlings again and start the cultivation of the next cycle. There must be a long fruitless period in the middle, or called an invalid period. Not only the yield is affected, but also Increased labor intensity and increased capital investment
