Novel seedling raising method for grape hybrid seeds

Abstract

The invention relates to a novel seedling raising method for grape hybrid seeds. Seedling raising is conducted on hole trays in seedling raising pits. The method comprises the specific steps that 3-5layers of plastic thin films are used for wrapping the grape hybrid seeds for sealing, the grape hybrid seeds are placed in a refrigerator at 1-7 DEG C and refrigerated for more than 4 months, beforesowing, the hole trays are placed in the seedling raising pits, the seeds are soaked in a gibberellic acid solution for 6-8 hours and then sowed in the hole trays, plastic sheds are built on the upperportions of the interiors of the seedling raising pits, sunshade nets cover the upper portions of the interiors of the seedling raising pits, the temperature in the sheds is controlled within 20-28 DEG C, and watering is conducted in the seedling raising pits through a mode that the water surface is 1-1.5 cm lower than the top surfaces of the hole trays. The seedling raising pits are rectangularpits which are dug on the ground, the depth of the pits is 10-15 cm, the width of the pigs is 3-5 cm larger than that of the hole trays, and a drainage ditch with the depth larger than that of the seedling raising pit is dug nearby each seedling raising pit. According to the method, seedling emergency can be advanced by 7-10 days, the seedling raising period is short, the water-retaining propertyof the seedling raising pits is good, the watering frequency is lowered, the production cost is lowered, the seedling emergency rate is above 80%, and the seedling planting rate is above 90%.

Description

technical field [0001] The invention relates to the technical field of viticulture. Background technique [0002] Raising grape seedlings is usually a method that is often used when cross-breeding, seed selection, and wild resources are utilized as rootstocks. Grape seed seedlings usually adopt soil sowing seedlings, nutrient pot seeding seedlings, and seedling tray seedlings in a solar greenhouse or in a greenhouse. There are following deficiencies in these seedling methods, soil sowing and seedling cultivation: the one, the emergence rate is low; The rate is low, and the slow seedling period is long, thereby affecting the growth of the year (this problem is more prominent when encountering high temperature weather when transplanting).

AI Technical Summary

Problems solved by technology

There are following deficiencies in these seedling methods, soil sowing and seedling cultivation: the one, the emergence rate is low; The rate is low and the slow seedling period is long, which affects the growth of the year (this problem is more prominent in high temperature weather when transplanting)

However, the main problem of nutrient pot seedlings is that it is labor-intensive to install the substrate or nutrient bags, and the placement is uneven, the emergence rate is relatively low, and it is easy to mix when transplanting.

It is labor-intensive and time-consuming to water the seedlings in the solar greenhouse or in the greenhouse. It needs to be watered almost every day during the whole seedling cultivation period. When the temperature is high, it even needs to be watered once a day in the morning and evening. Seedlings that fail to emerge or die
