Three-dimensional frame type cultivation method for watermelons

Abstract

The invention provides a three-dimensional frame type cultivation method for watermelons. The three-dimensional frame type cultivation method comprises the following steps: greenhouse construction, fertilizer application before planting, seeding and transplanting, vine hanging, double-vine type pruning and drip-irrigation management, wherein the step of double-vine pruning comprises the followingsubsteps: carrying out pinching when a plant grows 5 leaves, then remaining two secondary vines every plant, separately introducing and tying the secondary vines onto a nylon rope, when each secondaryvine grows 4 leaves, carrying out pinching and remaining a third vine every secondary vine, and when each third vine grows 2 to 5 leaves, carrying out pinching and remaining a fourth vine every thirdvine, and allowing each plant to bear watermelons for three times and each vine to bear a watermelon. By adoption of the three-dimensional frame type cultivation method provided by the invention, thewatermelons can achieve the following excellent growth effects: rapid plant growth speed, ventilation and light transmission, healthy and strong growth, slight occurrence of diseases and pests, highwatermelon bearing rate, tidy watermelon shape and excellent watermelon quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a three-dimensional rack cultivation method for watermelon. Background technique [0002] Watermelon is an annual vine of Cucurbitaceae; the stems and branches are thick and have obvious edges. The tendrils are thick, pubescent, with thick petioles and densely pilose; the leaves are papery, triangular-ovate in outline, with white-green, heart-shaped at the base of the leaves. Monoecious plants, all solitary in leaf axils, pedicel of male flowers 3-4 cm long, densely covered with yellow-brown villous hairs; calyx tube broadly bell-shaped; corolla light yellow, stamens nearly free, filaments short, herb cells curved. The calyx and corolla of the female flower are the same as the male flower, the ovary is ovate, and the stigma is reniform. The fruit is large, nearly spherical or oval, fleshy, juicy, smooth, with various colors and patterns. The seeds ...

Problems solved by technology

Although it has the advantages of cost saving and extensive management, but the disadvantages are obvious, which are manifested in the following aspects: first, it is greatly affected by the natural climate, especially in the case of strong winds and heavy rains in the open field, which will seriously affect the normal growth and flowering; The shape and quality are inconsistent, so the difference is large, which limits the potential for increasing production and quality; the third is serious pests and diseases, such as anthracnose, fusarium wilt, blight, mites, aphids, etc.
