Problems solved by technology

[0002]At present, most tomato nutrient solution formulas are general-purpose formulas or single-substrate nutrient solution formulas, but lack specific formulas for composite substrates, especially rock wool, which is expanding in size day by day. The specific formula for the composite matrix of coconut bran is still blank; in addition, the different growth stages of tomato growth have great differences in the requirements for various elements, and the existing tomato nutrient solution formula is one formula for the entire growth cycle, which is difficult to meet the needs of tomato. The demand for nutrient elements at different growth stages leads to frequent occurrence of nutrient deficiency symptoms in soilless cultivation
[0003]With the adjustment of the rural industrial structure, the protected cultivation of vegetables, fruits and flowers has developed rapidly, which has greatly enriched the vegetable basket and people's lives, and has become an important agricultural pillar Industry is an important way to increase farmers' income. However, due to the fixedness of facilities, the special ecology in the facilities and the particularity of soil water and salt movement, the degree of soil salinization in facility cultivation will increase with the increase in the service life of facilities. Intensified day by day, secondary salinization has become the main soil obstacle factor in protected cultivation, which greatly troubles the development of protected cultivation
Soilless substrate cultivation is an effective technical way to overcome this obstacle. In substrate cultivation, the nutrients required by crops basically depend on the supply of nutrient solution. At present, the preparation of nutrient solution is costly and low-efficiency, which has become one of the bottlenecks restricting the development of soilless substrate cultivation. , saving costs and increasing efficiency has become the key to the promotion of soilless cultivation

Embodiment 1

[0024] 1. Raw material selection

[0025] The raw material type of element source is selected as CaNO 3 .4H 2 o. EDTA-2Na, KNO 3 , MgSO 4 .7H 2 O. KH 2 PO 4 、K 2 SO 4 , ZnSO 4 .7H 2 O 、MnSO 4 .7H 2 O, CuSO 4 .5H 2 O. HBO 3 、Na 2 MoO 4 .2H 2 O has a total of 11 kinds of raw materials, a large number of elements are more than 95% pure for agricultural use, and the micro-fertilizers are chemically pure.

[0026] 2. Configuration method

[0027] ①Water: Purified pure water, EC is less than 0.02mS / cm, pH is around 5.8-7.0, and the mineral content meets the requirements of agricultural water.

[0028] ②Mother liquor preparation: According to the recipes of different periods, the raw materials are configured into two mother liquors A and B that are 200 times concentrated, and put into the A mother liquor tank and the B mother liquor tank respectively.

[0029] ③Configuration principle: A mother liquor is centered on calcium salt and chelated iron; B mother liquor ...

Embodiment 2

[0059] Three tomato varieties, "A", "B" and "C", which are special nutrient solutions for tomato coir peat and rock wool compound cultivation, performed well. The specific implementation plan is as follows:

[0060] 1. Seedling cultivation

[0061] ① Germination after scalding with high temperature:

[0062] When more than 80% of the tomato seeds are white, they can be sown. When sowing, use a key or tweezers to transfer the seeds to the rock wool plug, cover the surface with 0.8-1cm vermiculite and then cover with non-woven fabrics; Expand, the substrate temperature is 25°C, and the humidity is 90-95%.

[0063] ②Transfer to rock wool block (10cm×10cm):

[0064] Using root-cutting regeneration technology, transfer the rock wool plug to the rock wool block to increase the amount of root system and cultivate strong seedlings; water with EC2.0-2.5 and PH6.2 tomato nutrient solution in the early flowering stage and the control, then spray the top with clear water, and spray the...

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to a composite substrate cultivation nutrient solution of tomato, rock wool and coco coir. The composite substrate cultivation nutrient solution of tomato, rock wool and coco coir is characterized by being respectively prepared into a nutrient solution for an early stage of the bloom, a nutrient solution for 1-3 spike flower stages of the tomato, a nutrient solution for 4-5 spike flower stages of the tomato, a nutrient solution for 6-10 spike flower stages of the tomato, and a nutrient solution for 11-30 spike flower stages of the tomato according to different growth stages of the tomato. By adopting the nutrient solution disclosed by the invention, compared with the formula of a contrast nutrient solution, the tomato plant is robust, developed in root and upright in fruit; the yield per unit area is relatively higher than 3.5kg / m<2> and can be up to 33.6kgm<2>; the incidence of navel rot is relatively reduced by 10%; the upright degree of the fruit is high; the occupancy rate of the first-class goods fruit is relatively improved by 5%.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a nutrient solution for tomato rock wool and coconut bran composite substrate cultivation. Background technique [0002] At present, the tomato nutrient solution formula is mostly a general formula or a single matrix nutrient solution formula, but lacks a specific formula for a composite matrix, especially the specific formula for a composite matrix of rock wool and coconut bran that is expanding in size is still blank; , the different growth stages of tomato growth have great differences in the demand for various elements, and the existing tomato nutrient solution formula is a formula for the entire growth cycle, which is difficult to meet the needs of different growth stages of tomatoes for nutrient elements, resulting in frequent soilless cultivation. Deficiency symptoms occur. [0003] With the adjustment of the rural industrial structure, the facility ...
