Problems solved by technology

[0004] Traditional seedling cultivation methods include: seedbed selection, leveling, fertilization, plowing, seed sowing, control of planting density, soil covering, watering, heat preservation, weeding, thinning, seedling setting, pest management and other complex procedures. Therefore, due to the restrictions that the seedling land should be near the cultivation land, there is a seedling return period for transplanting, and the seedlings are not suitable for long-distance transportation

Embodiment Construction

[0040] The technical solution of the present invention will be further analyzed and illustrated through specific examples below.

[0041] The floating seedling raising method that is applicable to sweet sorghum cultivation in the present embodiment is as follows:

[0042] 1. Selection of seedling trays

[0043] The seedling tray (floating tray) is made of foamed polystyrene material. The seedling tray has a variety of specifications. At present, the most widely used seedling trays on the market are 200-hole and 178-hole seedling trays. It is recommended to choose white 178-hole and less Hole seedling trays are used to cultivate strong sweet sorghum seedlings with more roots.

[0044] 2. Selection of seedling substrate

[0045] The seedling substrate is generally obtained locally, and the soilless light substrates such as peat and vermiculite are mixed and prepared in equal volumes, or the finished soilless light substrates are used.

[0046] 3. Selection of nursery sites

Abstract

The invention discloses a floating seedling raising method suitable for sweet sorghum cultivation. The method utilizes the characteristics of waterlogging resistance and drought tolerance of sweet sorghum, aims at shortcomings of a seedling raising manner in a traditional seedling raising land and uses floating seedling raising methods of flue-cured tobacco and other sorghum planting for referenceto develop the floating seedling raising method suitable for the sweet sorghum. The method disclosed by the invention refines seedling raising operation procedures, and has the advantages of being suitable for longer-distance transportation and suitable for commercialized seedling raising, improving a survival rate of transplanting, having simple seedling raising management, saving labor and time, and basically having no seedling recovering stage after transplanting.

Description

technical field [0001] The invention relates to a floating seedling raising method suitable for sweet sorghum cultivation, which belongs to the technical field of crop cultivation. Background technique [0002] Sweet sorghum, its systematic classification is Gramineae Sorghum family Sorghum genus Sorghum sweet sorghum cultivar (Sorghum bicolor (Linn.) Moenchsubsp, bicolor'bicolor') with high sugar content in sweet sorghum subspecies planted sweet sorghum, its biological yield And straw sugar content is extremely high. Sweet sorghum has strong adaptability, drought resistance, waterlogging tolerance, and well-developed root system. It is an efficient and water-saving crop, an energy crop with high biological yield, and an excellent animal husbandry crop. Promoting the cultivation of forage sweet sorghum can effectively solve the serious shortage of forage caused by rapid development; after pressing the stalks of alcohol sweet sorghum, the juice can be used as industrial raw ...
