[0038] A nutrient solution for soilless cultivation of fruits and vegetables, the components of which are composed of A-type elements, B-type elements, C-type elements, D-type elements, E-type elements and F-type elements, and A, B, and C in each liter of nutrient solution , D, E, F class element each raw material weight ratio is:

[0039] Type A elements: calcium nitrate tetrahydrate 440-460, potassium nitrate 400-410, potassium dihydrogen phosphate 120-130, magnesium sulfate heptahydrate 235-255, ammonium humate 700-800;

[0040] Type B elements: sodium iodide 0.18-0.22, boric acid 1.3-1.5, manganese sulfate 0.8-1.0, zinc sulfate 0.12-0.14, sodium molybdate 0.01-0.012, copper sulfate 0.045-0.055, cobalt chloride 0.01-0.012, benzoic acid 0.2-0.3;

[0041] Type C elements: disodium edetate 5.6-5.8, ferrous sulfate 4.4-4.6;

[0042] D elements: glycine 0.6-0.8, thiamine hydrochloride 0.09-0.11, pyridoxine hydrochloride 0.38-0.42, niacin 0.38-0.42, pyraclostrobin 2.5-3.5, thir...

Embodiment 2

[0062] At the beginning of March 2014, the tomato variety "Yu Fen No. 2" and the pepper variety "Ruiqi" with a wide planting area in Lianyungang were respectively selected, and the classical hydroponic formula invented by Knop in 1865 (see Table 1 below) was used as the nutrient solution for greenhouse cultivation. Soilless cultivation test, the planting area was 0.1 mu each, the planting period and cultivation method were the same as in Example 1, and the colonization survival rate, fruiting period, and single fruit weight of the tomato variety "Yufen No. 2" and the pepper variety "Ruiqi" were respectively investigated and counted. , Yield per mu and drug cost per mu.

Abstract

A soilless culture nutrient solution for fruits and vegetables is provided. The soilless culture nutrient solution comprises A type elements, B type elements, C type elements, D type elements, E type elements and F type elements, and is prepared into three nutrient solutions for an early planting period, a later planting period, a culturing and growing period, and the like according to different needs of fruits and vegetables in the different growth stages. During preparation, the A type elements, the B type elements, the C type elements, the D type elements, the E type elements and the F type elements are respectively prepared into stock solutions, the stock solutions are diluted in clean tap water according to ratios in order and fully stirred and then pH is calibrated. The soilless culture nutrient solution meets nutrient requirements of the fruits and vegetables in each growth and development stage, improves immunity of the fruits and vegetables, reduces the occurrence rate of diseases and pest diseases, and greatly reduces pesticide spraying, thus increasing the yield, improving quality and reducing the cost. The soilless culture nutrient solution meets the development direction of organic agriculture and ecological agriculture.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation of fruits and vegetables, in particular to a soilless cultivation nutrient solution for soilless cultivation of fruits and vegetables with high survival rate, improved quality, and strong resistance to diseases and insect pests, thereby increasing the yield of fruits and vegetables, high quality, and reducing costs . Background technique [0002] Soilless cultivation refers to the planting technology that does not use natural soil to cultivate plants, but uses nutrient solutions containing elements necessary for plant growth and development to provide nutrition and enable plants to complete the entire life cycle normally. It has changed the traditional planting habit of agricultural production relying on soil since ancient times, greatly promoted the vigorous development of modern agricultural science and technology, and promoted the transformation of agricultural production to a new ...
