Description
Technical Field
The invention relates to the technical field of soilless culture, in particular to a formula and a preparation method of a special nutrient solution for soilless culture.
Background
Soilless culture vegetables and fruits are not cultured in soil, but seedlings of crops are planted in an aqueous solution (a nutrient pool) dissolved with mineral substances, or the crops are cultured in a certain culture medium by using a nutrient solution. The crops can grow normally and obtain high yield as long as certain cultivation equipment and management measures are provided.
The soilless culture is characterized in that the artificially created root growth environment of the crops replaces the soil environment, the requirements of the crops on the conditions of nutrients, moisture, air and the like can be met, and the soilless culture can be regulated and controlled, so that the crops can grow better, the yield is high, and the quality is good!
Although soilless culture is a young science, the soilless culture has been developed and applied to many fields, the soilless culture and the soilless culture have many advantages that the soilless culture and the water and fertilizer are integrated, and nutrient solution is inseparable. The method needs to really screen a good formula through own practice and exploration, so the composition and the change rule of the nutrient solution must be known from theory and practice, and the good effect can be obtained only by flexibly and correctly using the nutrient solution in complex production practice, and the existing nutrient solution formula is reported to be a fruit and vegetable soilless culture nutrient solution, and the formula of Kawasaki (1978) has the following major elements: NH 4-N1.0mmoll-1; NO 3-N10.0mmolel-1; s1.0 mmol-1; p0.49mmolel-1; k3.48mmoll-1; mg1.0 mmol-1; ca1.0mmolel-1. The formula belongs to a high N, K formula, and the content of P, Ca is relatively low, so that the formula is not suitable for the current commercial demand.
The other formula is a fruit and vegetable broad-spectrum formula published by southern China agricultural university (1990), and the major elements of the formula are as follows: NH 4-N0.0mmoll-1; NO 3-N8.0mmoll-1; s1.0 mmol-1; p0.17mmoll-1; k2.22mmoll-1; mg1.0 mmol-1; ca1.0 mmol-1. The total salt concentration of the formula is lower, and particularly the content of P is lower.
In general, the two nutrient solutions have the defects of low content of Ca and P, no formula value of trace elements and no corresponding formula technical scheme aiming at different growth periods, and the growth requirements of fruit and vegetable crops cannot be completely met.
