Problems solved by technology

In 2005, Chen Jinxiang and others applied for the patent of cotton hydroponic floating seedling raising method (application number: 200510031883.3), which greatly improved the emergence rate and seedling rate, but the requirements for sowing depth, substrate ratio, substrate water absorption and tray water entry depth were strict. , the technical difficulty is greater, and each link has a greater impact on the growth of cotton seedlings

Embodiment approach

[0014]Sowing period: When the daily average temperature is stable for 5 consecutive days above the biological starting point temperature of the seedling crops by 2-5°C, the seedlings can be sown.

[0015] Selected seeds: In order to improve the seedling rate, the seeds should be selected before sowing, and the large seeds should be selected by the grain selection method to select strong, plump and pest-free seeds, so that the germination rate of the seeds can reach more than 95%. The selected seeds are preferably sun-dried for 3 to 4 days in a row to promote post-ripening of the seeds and speed up the speed of germination and emergence.

[0016] Build nursery ponds or seedbeds filled with nutrient solution: the length of the seedbed filled with nutrient solution depends on the number of seedlings, generally 3-5m long and 50mm-200mm deep. Lay film (0.1mm thick) inside the bed to prevent water leakage.

[0017] Preparation of nutrient solution: Prepare a special nutrient soluti...

Abstract

The present invention relates to a new-type arid land crop seedling-cultivating method namely dry and wet two-stage tray seedling-cultivating method. It is characterized by that said method adopts porous tray, matrix and nutrient liquor. According to the biological characteristics of crop seed germination, emergence of seedling and young seedling growth, in the normal sowing season of arid crop the seedling-cultivating process from sowing to seedling transplantation can be divided into dry and wet two stages.

Description

technical field [0001] The invention belongs to a method for producing seedlings of dry soil crops, in particular to dry soil crops cultivated under non-flooded conditions during the whole growth period, including cotton, tobacco, watermelon, rape, peanuts, beans, peppers, melons and leaves For crops such as vegetables, a method for growing seedlings in dry and wet stages and a method for transplanting seedlings by using seedling trays, substrates and nutrient solutions. Background technique [0002] At present, in the cultivation of crops in dry soil, most of them use field direct seeding, and a few crops with high economic value and high seed production cost, such as cotton, tobacco, watermelon, etc., use seedling cultivation and transplanting, but the most common method of raising seedlings is dry seedling cultivation, that is, sowing Both the cultivation and seedling cultivation were carried out in the xerophytic ecological environment with non stagnant water and stagnan...
