Multi-stock grafting method for watermelon plant

Abstract

The invention provides a multi-stock grafting method for a watermelon plant. The multi-stock grafting method is characterized by comprising the following steps that a cotyledon with a growing point of both a pumpkin stock and a bottle gourd stock is obliquely cut off to form a tangent plane; the portion below a cotyledon of a watermelon scion is obliquely cut to form two tangent planes; the tangent plane of the pumpkin stock and the tangent plane of the bottle gourd stock are attached to the two tangent planes of the watermelon scion in an alignment mode, and then a grafted seedling is obtained after fixing. According to the multi-stock grafting method for the watermelon plant, one watermelon scion is grafted to two or three stocks combined by the pumpkin stock and the bottle gourd stock at the same time, difference complementarity of different stocks is utilized, multi-stock grafting advantages are achieved, the watermelon plant obtained after grafting is stronger in growth potential, the watermelon quality is ensured, and meanwhile the watermelon output is improved. In addition, the attaching connection method is adopted, one watermelon scion is grafted to two or three stocks at the same time, the operation steps are simple, and the requirement for the technical difficulty level is low.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a multi-rootstock grafting method of watermelons. Background technique [0002] Watermelon (Citrullus lanatus (Thunb.) Matsum.et Nakai) is an important horticultural crop widely cultivated in Cucurbitaceae melons, and it is also one of the main crops in protected cultivation. China is the largest watermelon producing area in the world, but in recent years, continuous cropping obstacles have become increasingly serious, especially soil-borne diseases, which have seriously affected watermelon absorption of water and fertilizer, reduced plant resistance, and affected the growth of watermelon plants. Cause yield reduction and quality decline, have hindered the development of watermelon production. Watermelon grafting cultivation is an effective technical measure to overcome continuous cropping obstacles and prevent the occurrence of Fusarium wilt. Appropriate root...

Problems solved by technology

The traditional grafting method is single rootstock grafting. Due to the limitation of germplasm resources, the role of many rootstocks is unique or specific.

For example, grafting with a single rootstock of pumpkin can make the root system develop, promote the absorption of fertilizer and water, and increase the stress resistance and fruit yield of the plant, but its appearance and commerciality will decrease, and the quality of flavor will decrease; using gourd as rootstock will have little impact on the quality of watermelon. However, the plant's disease resistance and stress resistance are slightly poor, which restricts the promotion of watermelon grafting cultivation technology
