Strawberry early vine-breaking cutting plug seedling method

Abstract

The invention discloses a strawberry early vine-breaking cutting plug seedling method. The method comprises the following steps of planting strawberry stock plants on high ridges in the middle and last ten days of March, and after the middle ten days of June, taking young seedlings which just spread leaves on strawberry stems and vines, and preferably appearing 2-3mm root protrusions on the stemsand vines at seedling growing positions. Enough seedlings are simultaneously inserted into a plug tray by refrigerating the seedlings, and water spraying after cutting, water spraying in a rooting stage and seedbed management are realized by arranging a seedbed and a micro-spray head; and when the strawberry seedlings have more than four expanded leaves and the rhizome thickness is more than 0.5 cm, the seedlings emerge, and seedling raising is completed. According to the strawberry early vine-breaking cutting plug seedling method, the problem of poor uniformity of seedlings in the same seedling tray can be solved, the management time in the strawberry seedling tray is shortened, the management cost is reduced, and the commodity rate of the seedlings is increased; the cuttage success rateis high, and the uniformity and strong seedling rate of the strawberry seedlings are high; and the number of germination new vines is large, and strawberries show good early maturity and high yield.

Description

technical field [0001] The invention relates to the technical field of strawberry seedling cultivation, in particular to a method for cultivating strawberry seedlings by early cutting and plugging. Background technique [0002] At present, asexual reproduction is adopted in strawberry production, that is, propagation with stolons. Generally, seedlings in sheds are used to grow seedlings in the fields. The mother plants are planted from mid-to-late April. , take root on the spot, form a small seedling, and then continue to send out stolons and elongate forward, so many new strawberry seedlings are formed repeatedly. Strawberry stolons are formed by the germination of axillary buds of new stems in the same year. They are the main vegetative reproductive organs of strawberries. Axillary buds germinate to produce stolons. In the early stage of growth, stolons grow upwards. , growing prostrate along the ground. A stolon is a uniaxial-sympodial branch, in most varieties, the axi...

AI Technical Summary

Problems solved by technology

[0004] In the middle and late June of each year, strawberry seedlings enter the period of frequent creeping vines. At this time, traditional field seedling cultivation adopts the operation of pressing seedlings for rooting, or introducing strawberry stolon seedlings to plugs or nutrient pots for fixed rooting. At this time, the operation of cutting vines is generally not adopted. , until the middle and late July, when the root system of the expanded strawberry stolons is fully developed, the operation of cutting the vines is adopted, so that the method of gradually pressing and expanding the seedlings in the plug tray will be formed, which will greatly lengthen the time occupied by the seedling space and increase the cost of the seedlings. Management labor costs, and there will be problems such as the coexistence of multi-level seedlings in one plug tray, and poor seedling uniformity

[0005] Strawberry production The number of strawberry seedlings planted per mu is large (about 8,500 plants per mu), and the traditional seedling propagation method is time-consuming, labor-intensive, and low input-output rate

At the same time, compared with solanaceous and melon vegetable seedlings, strawberry has a long time for seedling production (4 months), pressure and expansion, increasing number of seedlings, and small number of seedlings per unit area. Even if the current more advanced Strawberry hole-groove seedling propagation and plug-in plug-in tray seedling cultivation methods still have not solved the problem of long seedling propagation cycle and large area of ​​seedling propagation (according to the standard of 30,000 seedlings per mu, it only accounts for one-seventh of the intensive seedling cultivation of solanaceous fruits. 1) Poor uniformity of seedlings, root adhesion and other problems, so strawberry seedlings are still mainly self-propagating by farmers, which restricts the development of the strawberry industry
