Description
Technical field
The invention belongs to vegetable aquaculture fields, more particularly relate to a kind of nutrient solution prescription suitable for deep liquid stream water planting romaine lettuce
And ciltivating process.
Technical background
For soilless cultivation, nutrient solution is even more important.Especially mill water culture nutrient solution is even more the most important thing.It is big currently on the market
Part aqueous fertilizer be for various vegetables, but for the nutrient absorption of vegetables and growth cycle, the vegetables of different cultivars
The needs of nutrition are different.
Secondly requirement of the water planting to soil is lower, and many places in China lead to the soil salinization or mountain due to planting for a long time
Ground is not suitable for long-term cropping, and the appearance of water planting can solve this problem, improves the land utilization ratio in China.
With the development of the level of urbanization, indoor plantation becomes a kind of fashion, especially balcony vegetable aquaculture.But this
Kind plantation needs suitable nutrient solution.Current market sales of major part nutrient solution, various nutrient ratios are unreasonable, match
Than unbalance, or contain harmful substance, long-time service can affect to the growth of vegetable crop.
Existing romaine lettuce nutrient solution prescription growth growing way is weaker simultaneously, and blade is relatively thin and downy mildew and bacillary leaf rot
The higher highest of disease incidence can achieve 14%.A most important problem is that existing nutrient solution prescription growth has the tendency that excessive growth,
Blade is relatively thin, does not stand upright, and soluble solid content is lower, and commodity is poor.
Summary of the invention
To solve the problems, such as the above mill water culture nutrient solution, the object of the present invention is to provide a kind of battalion suitable for deep liquid stream water planting romaine lettuce
Nutrient solution, the formula is reasonable, nutrition is balanced and unharmful substance and can improve romaine lettuce yield and quality.
The present invention is the absorption characteristics by romaine lettuce to various nutrient elements, and addition amino acid improves the root growth of romaine lettuce
Environment achieves the goal of high yield and high quality.The configuration of nutrient solution first has in view of whether containing harmful substance to vegetables and the mankind
It causes centainly to injure, while should be based on chemical element, supplemented by microorganism formulation, i.e., a great number of elements, microelement, biology are made
Agent cooperates and provides a good growing environment jointly for root system.
Need to provide the properly nutrient solution prescription with deep liquid stream water planting thus.
To realize this purpose, the present invention adopts the following technical scheme:
