Abstract

The present invention relates to the field of a nutrient solution for soilless culture. Nutrient solutions sold in markets at present are all dilute solutions, and have the defects of large volume, pH value close to neutrality, easy occurrence of change in ion concentration and periodic replacement in the using process. The nutrient solution concentrate for soilless culture is 50 to 200 times as concentrated as common nutrient solutions, and the pH value is lower than 3. The nutrient solution concentrate has the advantages of easy packaging and transportation, stable ion concentration, little possibility of change, need of supplement instead of replacement while in use, little investment, easy operation, convenient management, long fertilization cycle, water saving and labor saving.

Description

Soilless culture nutrient fluid

The present invention relates to the field of soilless cultivation nutrient fluid.

The core of soilless culture is a nutritive medium, each interionic has certain equilibrium relationship in the nutritive medium, and each ion must keep certain concentration ratio, and commercially available nutritive medium all is a diluent at present, can directly use, need not dissolve and dilute, so volume is big, deal is heavy, pH value is near neutral, composition easily changes, and is difficult for preserving, and gives packed and transported, stores and bring inconvenience.In use, bigger variation can take place in each interionic balance, after for some time, nutritive medium is essential all to be changed, otherwise can constitute injury to plant, this has not only caused the waste of nutritive medium, also need increase certain detecting instrument and equipment, and requires producers to support to hold higher specialized technical knowledge.

The purpose of this invention is to provide a kind of packed and transported of being convenient to, be difficult for changing, still can keep various interionic equilibrium relationships, soilless culture nutrient fluid easy to use at the lay up period composition.

Technical scheme of the present invention is that soilless culture nutrient fluid is made underflow, concentrate 50-200 doubly than common nutritive medium, pH value reduces greatly, has guaranteed not change in transportation lay up period ionic concn, dilute according to spissated multiple during use, be diluted to the concentration range of service requirements.

Each concentration of element scope of nutrient solution liquid concentrate for soilless culture following (unit is ppm):

Ammonium attitude ammonia (N) 80-4950

Nitric nitrogen (N) 1010-22800

Phosphorus (P) 230-6000

Potassium (K) 2340-47700

Calcium (Ca) 0-8000 (hard water matter area does not add)

Sulphur (S) 600-14250

Magnesium (Mg) 300-7500

Boron (B) 0.5-75

Zinc (Zn) 1-39

Copper (Cu) 0.1-30

Molybdenum (Mo) 0.1-7.5

The blending process process is as follows:

1, the content according to each element takes by weighing corresponding pharmaceutical chemicals respectively.

2, first injection need be joined 2/3rds water of underflow volume in Agitation Tank.

3, nitrate is added jar interior a stirring, dissolving adds vitriol again and stirs, and dissolving is carried out under normal temperature, normal pressure.

4, will distinguish lysed ammonium salt, phosphoric acid salt, add in the jar respectively, stir evenly, under normal temperature, normal pressure, carry out.

5, add nitric acid.

6, add phosphoric acid.

7, molysite (ferrous sulfate), manganese salt (manganous sulfate), zinc salt (zinc sulfate), mantoquita (copper sulfate) are mixed the back dissolving.

8, with molybdenum compound (ammonium molybdate), boron compound (boric acid) dissolves respectively, carries out at normal temperatures and pressures.

9, the solution in 7,8 two steps is added in the Agitation Tank, stir evenly,

10, constant volume is added to the volume of required preparation with water, stirs evenly, and underflow is made.

The present invention has following characteristics: because of being the high power underflow, be easy to packing, transportation 1.; 2.PH the low underflow of value is easy to preserve, stable difficult variation of ionic concn; 3. because interionic equilibrium relationship is constant in use, nutritive medium only need replenish, and need not change; 4. less investment has been exempted the plant and instrument investment of nutrient management aspect; 5. simple to operate, do not need special training; 6. prolong about 60 times of fertilising cycles, labour 60% is saved in water saving 90%.

Embodiments of the invention 1:(cycles of concentration: 100, amount of preparation: 1 liter)

Each compounds content is: 2 milligrams of each concentration of element of underflow of ammonium sulfate 15.6 gram saltpetre, 82.4 gram 7 water magnesium sulfates, 30.8 gram phosphoric acid (85%) 8.6 gram nitric acid (66%) 18.4 gram 4 milligrams of permolybdic acid ammoniums of 44 milligram of 5 brochantite of 28 milligram of 7 water zinc sulphate of 182 milligrams of boric acid of 298 milligram of 4 water manganous sulfate of 7 aqueous ferrous sulfates are (unit is ppm) ammonium attitude ammonia (N) 3300 nitric nitrogens (N) 13800

Blending process is:

1, with every kind of compound by the consumption weighing that provides above, standby.

2, inject 2/3rds water (700 ml water) in Agitation Tank, add saltpetre, stir, the dissolving back adds sal epsom, stirring, dissolving, carries out at normal temperatures and pressures, approximately need stir and tremble all dissolvings after 20 hours.

3, ammonium sulfate dissolving back is added in the jar, stir about needs all dissolvings in 5 hours at normal temperatures and pressures.

4, add nitric acid, phosphoric acid, stir evenly.

5, ferrous sulfate, manganous sulfate, zinc sulfate, copper sulfate are mixed the back dissolving, with the permolybdic acid ammonium, boric acid dissolves respectively, and about half an hour is molten intact at normal temperatures and pressures.

6, the solution with 5 steps adds respectively in the jar, stirs evenly.

7, constant volume adds entry, makes solution amount reach 1 liter, stirs evenly and is the nutritive medium underflow, pH value＜3.

Can use after with hard water 100 times of underflow dilutions being stirred evenly during use, this prescription is suitable for hard water areas to be used.
