The so-called seedling raising in different places refers to the form of transporting vegetable seedlings cultivated in one place to other places (other provinces, cities, counties, etc.) for seedling raising. ) for field planting. For example, seedlings cultivated in large nursery farms (or nursery factories) are generally used to meet the needs of foreign production; Vegetable producers also need to buy seedlings from other places when they need them for various reasons. In foreign countries, there are specialized seedling companies to cultivate seedlings for sale for producers to buy, not only for foreign countries, but also for export to other countries. In China, in recent years, some areas with good seedling raising facilities and strong technical force have gradually developed seedling raising in different places. For example, Beijing, Shanghai and other places have established vegetable seedling centers to cultivate a large number of vegetable seedlings to meet the needs of producers, mainly fruit and vegetable seedlings, but also a small number of other vegetable seedlings. In addition, some areas have formed one or two vegetable seedling centers by using local characteristics and climatic conditions. For example, the cocoon area of Ruian City, Zhejiang Province, which is known as the hometown of cauliflower, cultivates a large number of cauliflower (hybrid) seedlings for the local area and northern Fujian, south-central Zhejiang and northeastern Jiangxi every year. In addition, in some new vegetable producing areas, because it is difficult for farmers to master the seedling raising technology, centralized seedling raising is generally adopted and uniformly supplied to vegetable producers.
The advantages of raising seedlings in different places are as follows: first, we can use the favorable local climate conditions to cultivate strong seedlings at low cost in simple seedling raising facilities; Second, we can give full play to the advantages of local technology and provide cheap and high-quality vegetable seedlings at a higher management level; Third, it is conducive to the promotion of improved vegetable varieties and accelerate the process of seedling integration; Fourth, solve the problems of facilities and management for producers to raise seedlings in small quantities. However, there are some difficulties in raising seedlings in different places, such as transportation problems, root protection measures, fresh-keeping technology and seedling packaging. Therefore, it is necessary to make use of possible conditions according to the specific situation in the seedling raising in different places to adapt the seedling raising in different places to long-distance and long-term transportation. Eggplant vegetables cultivated in spring and cabbage vegetables cultivated in autumn can be raised in different places. Pumpkins and leguminous vegetables are generally not suitable for raising seedlings in different places.
