Soilless culture nutrient solution for capsicum

Abstract

The invention discloses a soilless culture nutrient solution for capsicum, which belongs to the technical field of preparation of fertilizers for crops. 1 L of the nutrient solution comprises the following raw materials by weight: 700 to 850 mg of urea, 100 to 150 mg of calcium superphosphate, 110 to 150 mg of potassium dihydrogen phosphate, 230 to 250 mg of magnesium sulfate, 10 to 15 mg of ferrous sulfate, 1.5 to 3 mg of manganese sulfate, 0.2 to 0.4 mg of zinc sulfate, 0.05 to 0.09 mg of copper sulfate, 15 to 25 mg of disodium ethylene diamine tetraacetate, 2.1 to 3.6 mg of boric acid and 0.01 to 0.05 mg of potassium molybdate, with the balance being water. In the prior art, the nitrogen source of the soilless culture nutrient solution is normally nitrate nitrogen which is hardly available and has high cost, so great difficulty is brought to popularization and application of soilless culture; urea is used to replace nitrate nitrogen in the invention, so the advantages of low cost and the like are obtained; the nutrient solution is applicable to substrate culture of capsicum, can be used for topdressing by using drip irrigation facilities on the basis of application of a base fertilizer after float breeding and transplanting and enables soilless culture of capsicum to be easy, convenient and practical.

Description

technical field [0001] The invention relates to the field of crop fertilizer preparation, in particular to a nutrient solution for soilless culture of peppers. Background technique [0002] Pepper is a solanaceous vegetable, divided into "pepper" and "sweet and spicy". People are used to classify peppers according to whether they are spicy or not, and then divide them into "spicy peppers" and "slight peppers". Capsicum is a vegetable and seasoning that Chinese people like to eat, and it has even become a special hobby of people in some provinces (regions), and it has gradually spread throughout the country's urban and rural areas. Pepper is rich in nutrition and has high medicinal value. According to the measurement, the proliferating factors A and B contained in the fruit of pepper are higher than those of cucumber, tomato, eggplant and other fruits. Especially the content of vitamin C is higher than that of the above vegetables. It is 4-7 times higher, and every 100 grams...

Problems solved by technology

[0004] The object of the present invention is: for above-mentioned existing problem, provide a kind of capsicum soilless cultivation nutrient solution, solve the nitrogen source of soilless cultivation nutrient solution mostly to be nitrate nitrogen, its source is few, the problem such as high cost, the present invention adopts urea to replace Nitrate nitrogen has the advantages of low cost. This nutrient solution is suitable for capsicum substrate cultivation. It can be used for floating seedlings and after transplanting, use drip irrigation facilities as topdressing on the basis of base fertilizer application. It has the characteristics of simplicity and strong practicability
