Management methods of environmental factors in the process of raising green onion seedlings

Abstract

The invention discloses a method for managing environmental factors during Chinese onion seedling culture. The method comprises the steps of water management, light and temperature management, nursery soil management and weed management. Through precisely quantitative watering, water shortage during Chinese onion growth is effectively prevented. Through normalized light and temperature management, the Chinese onion growth environment is controlled strictly, illumination is utilized to the maximum extent, temperature and moisture suitable for growth and development of Chinese onion are maintained, the emergence rate is increased, and the occurrence rate of pest and disease damage is reduced. Through nursery soil management, photosynthesis is improved, the utilization rate of fertilizer is increased, growth of harmful bacteria is inhibited by means of other bacteria, and the morbidity of Chinese onion seedlings is reduced greatly. Meanwhile, through reasonable weed management, productivity is improved effectively, and the inhibition effect of weed on Chinese onion seedlings is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling raising, in particular to a method for managing environmental factors in the process of raising green onion seedlings. Background technique [0002] Scallion seedling cultivation is the basis of scallion cultivation. At present, the seedling raising technology of scallions in my country is still mainly based on the traditional open-air seedling raising method in the field, which is greatly affected by environmental conditions. The green onion seedlings bred are uneven, and the bud potential is weak. Seeing dry watering is not conducive to the growth of onion seedlings. At the same time, open-air breeding is adopted. Seedling management is basically "depending on the weather", which makes it difficult to manage light, temperature and humidity, and is greatly affected by external weather changes, which is very easy to produce Various pests and diseases, due to the weak control of enviro...

Problems solved by technology

At present, the seedling raising technology of scallions in my country is still mainly based on the traditional open-air seedling raising method in the field, which is greatly affected by environmental conditions. The green onion seedlings bred are uneven, and the bud potential is weak. Seeing dry watering is not conducive to the growth of onion seedlings. At the same time, open-air breeding is adopted. Seedling management is basically "depending on the weather", which makes it difficult to manage light, temperature and humidity, and is greatly affected by external weather changes, which is very easy to produce Various pests and diseases, the seedling period is prolonged due to weak control of environmental factors

At the same time, in the traditional seedling raising method, a large number of weed seeds of different types and different attributes are scattered in the seedbed. Under suitable conditions, the weed seeds germinate and grow, forming a "weed advantage", competing with onion seedlings for nutrients, inhibiting Onion seedling growth

Onion seedlings are weak and cannot use herbicides, and can only be weeded manually, which will consume time and effort, and will also have a certain impact on adjacent onion seedlings
