Problems solved by technology

[0003] However, in the process of planting citrus container seedlings, there are problems such as low seed survival rate, long cultivation period, easy loss of water in the seedling substrate, or too compacted soil. These problems seriously affect the growth quality of seedlings and restrict the development of citrus seedlings.

Abstract

The invention discloses a citrus seedling raising substrate and a seedling raising method thereof. Raw materials of the seedling raising substrate are millet, germanite powder and peat soil. The seedling raising method includes seed pretreatment, seedling raising substrate preparation, sowing, film covering and planting post-management. The technical effect obtained by adopting the technical scheme is as follows: seeds are pretreated by adopting ultrasonic waves, so that the germination rate of the seeds is increased; the composition and proportion of the seedling raising substrate are optimized to promote the germination and growth of seeds and shorten the cultivation period; film covering treatment is adopted to effectively improve the air, heat, water and fertilizer conditions of the soil and create a suitable environment for citrus growth; and the method is simple and convenient to operate and low in cost, and is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a citrus seedling raising substrate and a seedling raising method. Background technique [0002] Citrus, belonging to Rutaceae, is distributed at 16°-37° north latitude. It is a tropical and subtropical evergreen fruit tree. There are three genera used for economic cultivation, namely Citrus, Citrus and Kumquat. my country is the world's largest producer and consumer of citrus. In addition to being consumed as fresh fruit, citrus fruit is also an important raw material for processing, which can be used to produce canned food and orange juice. At present, the main citrus producing areas in my country, such as Chongqing, Jiangxi and other provinces and cities, have already planted citrus container seedlings on a large scale. Container seedlings refer to crops or seedlings of fruit trees, flowers and forest trees cultivated in specific containers. Planting citrus contain...
