Description

A kind of preparation method of fresh kidney beans grow seedling nutritional liquid

Technical field

The present invention relates to a kind of preparation method of fresh kidney beans grow seedling nutritional liquid.

Background technology

Culturing and transplanting seedlings has the compensating action of weather and the combined effect that makes crop growth do sth. in advance, and can make full use of sunlight-heat reaources, its economic benefit and social benefit are all fairly obvious.Adopt the planting patterns of culturing and transplanting seedlings in the plantation of China vegetables and cash crop always.Traditional seedling raising manners is the link that recruitment is maximum, labour intensity is maximum, main dependence manual work, until pot seedling buries from alms bowl operation processed, wherein involved links sow as being molded into alms bowl from soil screening, transport, alms bowl processed, apply fertilizer, the carrying of the pot seedling that waters and to transplanter divides seedling etc., almost all by completing by hand, labour intensity is large, time-consuming, inefficiency.For this reason, must to traditional seedling raising manners reform, implementing industrial seedling rearing is the inevitable choice improving China vegetables and yield of commercial crops.

Industrial breeding technique originates from the U.S. of the sixties in 20th century.Florida State Speedling company (U.S. support one's family seedling company) takes the lead in developing seed sower and hard plastic cave dish, for grow seedlings of vegetable.Industrial breeding technique found beginning, very soon by countries in the world as introductions such as Holland, Italy, Canada, Japan, Korea S.

Industrial seedling rearing realizes Vegetable produce to produce novel planting type to modernization, mass-producing and intensive conversion by traditional agriculture; seedling raising manners mechanize and intensive can be made; greatly reduce labour intensity; and be not subject to seasonal restrictions; can realize year-round supply, be the developing direction of grow seedlings of vegetable.
