Problems solved by technology

[0004] At present, most of the nutrient solution used in tomato rock wool substrate cultivation is a formula that can be used throughout the entire growth cycle. During the process, tomato plants often suffer from unbalanced nutrient supply, such as weak plant growth, lack of nutrients, premature aging, etc., which greatly affect the growth of tomato plants and the yield and quality of fruits.
In particular, there is no tomato-specific formula for rock wool substrate cultivation, which limits the promotion and application of tomato rock wool substrate cultivation to a large extent.

Embodiment 1

[0058] 1. Raw material selection

[0059] The raw material types of element sources are Ca(NO 3 ) 2 4H 2 O. KNO 3 , MgSO 4 ·7H 2 O. KH 2 PO 4 、K 2 SO 4 , NH 4 NO3 , EDTA-Fe13%, ZnSO 4 ·7H 2 O, MnSO 4 ·7H 2 O, CuSO 4 ·5H 2 O, H 3 BO 3 、Na 2 MoO 4 2H 2 O A total of 12 kinds of raw materials, all raw materials are of analytical grade.

[0060] 2. Configuration method

[0061] ①Water: The water used for tomato rock wool substrate cultivation must be purified water, the EC value of the water is required to be lower than 0.05mS / cm, the pH value is between 6.0-7.0, and the content of minerals and metal ions meets the agricultural requirements.

[0062] ②Mother liquor configuration: according to the wetness of the rock wool strips and the formula of the nutrient solution in different periods of tomato growth, the raw materials are respectively configured into two 100-fold concentrated mother liquors A and B, and are stored in the A mother liquor tank and the B mo...

Embodiment 2

[0098] Using the same raw material selection, configuration methods and principles of use as in Example 1, the special nutrient solution for tomato rockwool substrate cultivation was prepared to plant three varieties of tomatoes "A", "B" and "C", all of which performed well. The specific implementation plan is as follows:

[0099] 1. Seedling cultivation

[0100] ①Using the seedling raising technology of rock wool plug + rock wool block, the seeds are sown in the rock wool plug covered with vermiculite, and then placed in the germination room for germination. It is required that the day and night temperature of the germination room be kept at 25°C-28°C, and the substrate humidity be kept at 90%-95%. After the seeds germinate and emerge from the soil, move the seedlings to the nursery room for cultivation.

[0101] ② Transfer to rock wool block

[0102] When the leaves of the seedlings are in contact with each other, they are transferred to the rock wool block using root-cutt...

Abstract

The invention belongs to the field of crop cultivation and particularly relates to a tomato rock wool substrate culture nutrient solution. The tomato rock wool substrate culture nutrient solution is divided into six different nutrient solutions for rock wool moist, an early flowering period, a first to second spica flower period, a period after twelfth spica flower, a third to fourth spica flower period, a fifth to tenth spica flower period and an eleventh to twelfth spica flower period according to rock wool strip moist and different tomato growth periods. When the tomato rock wool substrate culture nutrient solution is applied to tomato rock wool substrate culture, the yield is improved by 10% or more and the first-class commercial fruit rate is improved by 5.0 percent or above compared with that of tomato rock wool substrate culture using a general soilless culture nutrient solution.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a tomato rock wool substrate cultivation nutrient solution. Background technique [0002] Tomato, commonly known as tomato and foreign persimmon, is an annual or perennial herb. It is a worldwide vegetable with high economic and scientific value. Since the end of the 1970s, my country has successively introduced various greenhouses of 60hm from developed countries. 2 , to build a solar greenhouse of nearly 100,000 hm 2 . The solar greenhouse has simple structure, good heat preservation and energy-saving effects, but the land utilization rate is low and the working conditions are poor. The land utilization rate of imported large-scale multi-span greenhouses and domestic large-scale multi-span greenhouses can be increased by more than 40%. The space is large, it is convenient for mechanized operations, and it has better production performance and greater production po...
