Problems solved by technology

With the improvement of people's living standards and the aggravation of the pollution of vegetable fertilizers and pesticides, the demand for green vegetables and food is increasing rapidly, and the vegetables grown in nutrient solution cannot be included in the organic green food, and the nutrient solution cultivation method requires large investment and relatively low technology. Complicated, not easy for ordinary farmers to grasp

Embodiment 1

[0015] 1) Preparation of fermented plant straw fibrous solid:

[0016] Crush plant stalks to make the particle size ≤ 3mm, add 3-4% of the straw weight by fast starter, cellulose decomposing agent, straw decomposing microorganism according to 1: 1: 0.1 and ferment for 7 days; then ferment for 7 days at a temperature of about 130 ° C 1. Vacuum concentration under the condition of 3.5 kg vapor pressure to make the water content 20% to obtain fibrous solid, which is set aside.

[0017] 2) Cultivate actinomycetes, nitrogen-fixing bacteria, and phosphorus bacteria into a liquid bacterial liquid according to a conventional liquid culture method, and prepare a microbial bacterial liquid according to a ratio of 1:1:1, and set aside.

[0018] 3) Sterilize the leftovers from milk factories and monosodium glutamate factories according to conventional methods, and deodorize them for later use.

[0019] Mix 3 parts of fibrous solids, 0.018 parts of microorganism liquid, 1.5 parts of milk ...

Embodiment 2

[0022] 5 parts of fibrous solid, 0.03 part of microbial bacterial liquid, 1 part of monosodium glutamate milk waste, 0.12 part of medium and trace elements.

[0023] After testing: it contains 8% humus, 14% organic matter, 11% total nitrogen + total phosphorus + total potassium, 5% amino acid, and 2% trace elements.

[0024] Test situation:

[0025] Compared with the conventional nutrient solution, the cucumber planted by the invention can increase the yield by more than 10 percent; the tomato planted can increase the yield by 21 percent, and the deformed fruits can be reduced.

Abstract

The invention relates to a nutrient medium for organic vegetable soilless cultivation, which comprises 3-6 parts of fermented vegetable stalk fibrous solid, 0.018-0.03 part of microbiological liquid bacterial, 1.0-15 parts of milk glutamate leftover bits and pieces, and 0.10-0.12 part of microelements.

Description

technical field [0001] The invention belongs to a soilless cultivation substrate, in particular to a nutrient substrate suitable for the soilless cultivation of organic vegetables. Background technique [0002] As we all know, soilless cultivation technology can effectively overcome continuous cropping obstacles such as floating salt on the soil and soil-borne diseases in vegetable protection cultivation. Since the advent of soilless cultivation technology, it has received the attention of various countries and has developed rapidly. [0003] At present, soilless cultivation technology has been widely used. In my country, substrate cultivation is the main method, and the commonly used form is to irrigate with organic or inorganic substrate and nutrient solution prepared by inorganic fertilizers. With the improvement of people's living standards and the aggravation of the pollution of vegetable fertilizers and pesticides, the demand for green vegetab...
