Method for improving seedling emergence of strawberry seeds

Abstract

The invention relates to a method for improving seedling emergence of strawberry seeds. The method comprises the following steps of: scattering the strawberry seeds in a seed tray with wet nutritional soil directly and uniformly; placing the seed tray into a tray with water which is 2 to 3 centimeters deep and raising seedlings for 1 month under the condition of natural weather and by a water bath method; and when seedlings grow true leaves, dividing the seedlings according to one plant in one cavity by using a cavity tray, wherein the seed tray is 15cm*20cm in caliber and 9 to 10 cm in height; water-permeating holes with the diameter of 0.2 cm are formed at the bottom at the interval of 20 cm; the nutritional soil comprises turfy soil and pearlite according to the volume ratio of 7:3; at least one seed tray is placed in the tray; and after the seedling grows 2 true leaves, the seedlings are divided according to one plant in one cavity. Soil moisture seedling is performed by the water bath method instead of the traditional soil moisture method; the seedling-raising method is simple and convenient, low in production cost and high in operability; and the rate of emergence of the strawberry seeds is increased, so that the efficiency of the conventional strawberry hybridization breeding is improved.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a method for improving seedling emergence of strawberry seeds. Background technique [0002] Strawberry, a perennial herb belonging to the family Rosaceae, is known as the "Queen of Fruits" and is widely cultivated in many countries in the world. It is planted as far as Fujian in the south and Heilongjiang in the north in my country. The continuous improvement of strawberry varieties is the basis for the development of strawberry production and its processing industry. From the 19th century to the present, more than 2,000 strawberry varieties have been bred in countries all over the world. Introduced and cultivated, or used as breeding resources, and further selected and bred new varieties suitable for production in various countries. Hybrid breeding is the main way to breed new varieties of strawberry at home and abroad. So far, most of the varieties bred at home and abroad come fr...

Problems solved by technology

[0008] Among the three methods, method 1 and method 2 are relatively simple to operate and highly operable, but their emergence rate is relatively low, only about 40%, and they need to be kept warm and moisturized after sowing and before transplanting. , the management is relatively complicated; although method 3 effectively improves the germination rate of seeds, sometimes even reaching more than 90%, but because it requires training and transplanting, if the training and transplanting are improper, it will have a great impact on the seedling rate. In addition, this method The operation process is relatively complicated, and requires high operating ability of the operator. In addition, because the method needs to be carried out under sterile conditions, it is laborious and laborious, the cost of seedling cultivation is high, and the efficiency is very low

[0009] The traditional method of soil moisture retention generally uses manual or watering equipment to regularly moisturize the soil or use a soil water-retaining agent made of a high-molecular polymer with a high water-absorbing and water-retaining capacity made of a strong water-absorbing resin. There are high requirements, and artificial moisturizing needs to be carried out regularly. Not only is the efficiency low, and the humidity is difficult to control, but it is also easy to miss or over-water to reduce the emergence rate. In addition, frequent watering, because strawberry seeds are small, the seeds are easy to be washed into the soil The depth of the layer cannot germinate, which affects the emergence rate

However, the cost of using watering equipment to moisturize the soil on a regular basis is too high, and because the general watering equipment in my country is relatively simple, it is easy to cause waste of water resources. If soil water-retaining agents are used for moisturizing, although they hold water well and have high water utilization efficiency , but due to the slow development of related technologies in our country, the soil water-retaining agents used in my country are relatively inferior and easy to pollute the soil, while foreign soil water-retaining agents are relatively expensive and costly
