Embodiment 1

[0090] Embodiment 1, a kind of nutrient set meal that takes sand, coal cinder as substrate cultivation tomato, said set meal includes the following components: special nutrient solution, functional fertilizer and new pesticide combination;

[0091] The formula of the special nutrient solution is: (mg / L) total nitrogen 176, phosphorus 45, potassium 180-350, calcium 90-160, magnesium 60, iron 0.85, manganese 0.55, zinc 0.33, boron 0.3, copper 0.05, Molybdenum 0.05.

[0092] The special nutrient solution is used to cultivate tomatoes with the help of a certain substrate. The substrate is sand and cinder, and the ratio of sand and cinder is optimized through experiments. The appropriate ratio is: when the particle size of cinder is 0.3 When -1 cm, it is mixed with river sand, river sand: cinder is (3:2)-(2:1), and the particle size range of the river sand is 0.5-1.5 mm. Simple use of special nutrient solution requires 750 jin of nutrient solution fertilizer per mu per year. If th...

Abstract

The invention provides a nutrition composition for cultivating tomatoes by using sand and coal residue as a matrix, wherein the nutrition composition comprises a special nutrition solution, a functional fertilizer and a novel pesticide combination, wherein the components of the formula of the special nutrition solution comprise, by weight, 176 mg / L total nitrogen, 45 mg / L phosphorus, 180-350 mg / Lpotassium, 90-160 mg / L calcium, 60 mg / L magnesium, 0.85 mg / L iron, 0.55 mg / L manganese, 0.33 mg / L zinc, 0.3 mg / L boron, 0.05 mg / L copper and 0.05 mg / L molybdenum, and the functional fertilizer comprises, by weight, 100 g / L amino acid, 2 g / L alginic acid and 5 g / L chitosan. According to the present invention, the tomato planted with the nutrition composition has the brown fruit rate of 1% and the sugar content of 4.7%, and the annual yield per mu is increased by more than 2500 kg.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a nutrition set, in particular to a nutrition set for cultivating tomatoes with sand and cinder as substrates and an application thereof. Background technique [0002] The use of river sand and coal cinders as a substrate for cultivating tomatoes has a history of many years in my country, but it has only been used in agriculture on a large scale for more than ten years. This method of soilless cultivation of tomatoes requires less spraying, high-quality products, and good taste, and is favored by consumers. The sales price is about 0.5 yuan per catty higher than that of tomatoes produced in the soil. Due to the low investment in the construction of such soilless cultivation facilities, simple operation, water saving, fertilizer saving, good quality, and relatively high income, it is very suitable for the current rural economic situation in our country, so it has de...
