What are the requirements for fertilizer for drip fertilization

Generally, instant fertilizers such as flush fertilization are used.

Precautions for drip fertilization.

1. Be sure to install a filter. The water source must be filtered, commonly used 100 mesh nylon mesh or stainless steel mesh; Or use a 120 mesh laminated and mesh filter. This is key to the proper functioning of the drip irrigation system.

The filter should be cleaned regularly; The end of the drip irrigation pipe is opened and flushed regularly, usually once a month.

2. Before fertilization, turn on the switch of the area to be fertilized for drip irrigation. Then dissolve the fertilizer in the fertilizer pond and start fertilizing after drip irrigation for 20 minutes. The fertilization time in each zone is about 30-60 minutes, and the fertilization speed and fertilization time are adjusted by the switch.

3. After fertilization, drip irrigation can not be turned off immediately, and sufficient time should be ensured to flush the pipeline, which is an important measure to prevent system blockage. The flushing time is related to the size of the irrigation area, and drip irrigation is generally 15-30 minutes to completely drain the fertilizer in the pipe. Otherwise, algae, moss, microorganisms, etc. will multiply at the dripper and clog the dripper.

4. Choose fertilizers with good solubility. With high nutrient content, good solubility and easy application, it is the preferred fertilizer for drip irrigation systems.

5. Adjust the amount of fertilizer appropriately. For first-time users of drip irrigation, the amount of fertilizer is adjusted on the basis of previous years, and then the "small amount and multiple times" method is used to apply fertilizer dripping.

6. Frequently go to the field to check whether there is water leakage, pipe blockage, pipe breakage, pipe cracking and other phenomena, and maintain the system in time.

Due to the developed root system of peach trees and the large single water demand, it is best to use drip irrigation to fertilize around the tree, and each tree is equipped with 4 6 drippers, and the water output of each dripper is about liter hours. For orchards with medium fertility of medium and late maturing varieties, the following drip fertilization scheme is adopted, and the yield can reach 1500 2000 kg mu. Early maturing varieties can reduce the amount of irrigation and fertilizer appropriately.

1) Before germination, 50 60 kg of ternary compound fertilizer (20-10-20) and drip irrigation of 25 30 m 3 mu were applied in the form of radial furrow or annular furrow fertilization to improve soil water content and promote germination, flowering and new shoot growth.

2) drip irrigation 2 3 times in the hard core period, 15 25 meters 3 mu each time, combined with drip irrigation fertilization 1 2 times, each drip application of water-soluble formula fertilizer 10 15 kg mu, N P2O5 K2O ratio to 20 10 10 is appropriate.

3) Drip irrigation 2 3 times during the fruit expansion period, each irrigation 15 25 m 3 mu, combined with drip irrigation fertilization 1 2 times, each drip application of water-soluble formula fertilizer 10 15 kg mu, the ratio of n p2o5 k2o should be 19 8 27.

4) During the maturity period, drip irrigation 1 2 times according to soil moisture, without fertilization. In autumn, before picking fruits and falling leaves, 3000 4000 kg of rotted organic fertilizer is applied per mu. From late October to early November, drip irrigation of 30 40 meters and 3 acres ensures that the soil has sufficient moisture, which is conducive to the safe wintering of peach trees.

Water-soluble fertilizers.

Drip irrigation is a form of micro-irrigation, which is a drip irrigation method in which the water is pressurized, filtered, delivered to the dripper through a low-pressure pipeline, and drip into the roots of crops in a drip manner.

Only the water-soluble chemical fertilizer and organic fertilizer leaching solution can drip irrigation, and pay attention to the spraying concentration, the concentration is too high to cause"Burn seedlings"。A small amount of neutral laundry detergent should be added when simply spraying a large number of elemental fertilizers to increase the adhesion and improve the effect of spraying. Foliar spraying of phosphorus and potassium fertilizers should be used in the young fruit stage of fruit and melon vegetables.

Drip irrigation fertilization is an irrigation and fertilization technology that uses drip irrigation system to dissolve fertilizer in water with the help of fertilization device, so that the fertilizer-water mixture is applied to the soil in the root zone of crops in the form of drops through the water pipeline. Compared with traditional irrigation and fertilization, drip irrigation fertilization can achieve local irrigation and fertilization, and improve the utilization efficiency of water and fertilizer. Drip fertilization has the following advantages:

Realize local irrigation and fertilization, which saves about 50% of water and 30% of fertilizer compared with conventional irrigation; reduce air humidity and crop diseases; reduce deep seepage of irrigation water and groundwater contamination; It is conducive to maintaining good soil structure and reducing soil degradation; Drip irrigation and fertilization can be carried out at the same time as other agricultural operations, saving labor; It is beneficial to improve crop yield and quality. The disadvantage of drip irrigation fertilization is that it requires a certain amount of equipment investment, and the later operation requires a certain amount of maintenance and management work.

Prepare a plastic bottle of about 2L, pinch four or five holes in the cap, and cut off the length of the bottom. Dig a hole in the soil and bury half of the bottle in the soil, keeping a distance of 10-15 cm from the plant. Insert the bottle into the hole with the opening facing down, fill the bottle with water and fertilizer, and let it drip irrigate.

The fertilizer applicator is mainly used for crop fertilization, through the fertilizer applicator can greatly improve the work efficiency and results, after years of development, the fertilizer applicator has also been greatly improved, the overall operation is convenient, and the small size can directly fertilize the roots of crops.

Features of the fertilizer applicator.

The fertilizer applicator is divided into two types: fertilizer suction and fertilizer injection, fertilizer suction is to use a specific device to generate negative pressure in a certain place of the irrigation pipeline, suck the fertilizer solution into the pipeline, mix it with irrigation water, and send it to the root zone of the crop.

Fertilizer injection is an external power that injects the fertilizer solution into the pressure management and mixes it with the root irrigation water to reach the root zone of the crop. When using, it can be carried out by pump fertilizer suction method, electric sprayer artificial fertilizer injection method, venturi fertilizer method, bypass fertilizer tank, etc.

1. Differential pressure fertilization method. Differential fertilization is the most common fertilization method commonly used in drip irrigation systems. It consists of a closed fertilizer tank connected in parallel to the dry pipe of the drip irrigation system.

This fertilization method is simple in structure, easy to use, and has little head loss. The method of use is to adjust the opening degree of the pressure regulator after injecting human solution into the tank to change the pressure difference between the inlet and outlet pipes of the fertilizer tank. At this time, most of the incoming water flows into the drip irrigation system along the main pipe, and a small part of the incoming water flows into the human fertilizer tank and is re-injected into the human main pipe by the outlet pipe after the solution in the tank is glued.

Therefore, the water containing chemical fertilizer components flows through the dense pipeline network in the field, and finally reaches the root zone of the crop, obviously, because in the fertilization process, the water without fertilizer continues to enter the fertilizer tank, therefore, the fertilizer concentration in the tank will be lower and lower, so that the uniformity of fertilizer concentration over time can not be achieved. In addition, the fertilizer tank is usually made of metal shell, although the inside of the tank is treated with anti-rust, but after a long time, the shell can still corrode and rust, therefore, a large number of iron ions into the drip irrigation system and the negatively charged soil colloids in the water combine to produce precipitation, thereby increasing the possibility of dripper blockage.

2. Pump-sucking fertilization method. The pump-suction fertilization method is only suitable for centrifugal pump water supply systems with negative pressure characteristics on the inlet pipe side of the pump. That is, a small pipe of 15 20 is separated on the side of the inlet pipe of the water pump, and the small pipe is passed into the fertilizer pool (tank).

When the water pump is running, the negative pressure of the water inlet pipe is used to absorb the fertilizer solution while absorbing water, and it is mixed by the water pump and transported to the field together. Pump-and-suction-based fertilization is an ideal and easy method of fertilization, but it is limited by the conditions of use.

3. High-level fertilization method. In hilly areas, it is common to encounter natural conditions where the irrigation water source is located at a high place, while the irrigation area is at a low place. At this time, the high-level fertilization method can be considered, and a fertilizer inlet pipe can be connected at the appropriate position of the main pipe and connected with the fertilizer solution container.

The fertilizer container is required to be placed in a higher position, so that the liquid level is higher than the water surface of the pressure measuring pipe in the main pipe, so that the solution can automatically flow into the main pipe by its position, and flow into the field together with the irrigation water. This ideal method of fertilization is also limited by the conditions of use.

4. Pumping man-type fertilization method. The pump-type fertilization method uses a micro-pump with high pressure and low flow to press the prepared fertilizer solution into the dry pipe of the drip irrigation system. Although this fertilization method is easy to control the fertilizer concentration, it increases the equipment investment and additional energy consumption.

5. "Throat" tube fertilization method, "throat" tube fertilization method is a fertilization method that applies the venturi principle. That is, a section of pipe section that gradually shrinks and spreads is installed in the water pipeline, and a fertilizer suction pipe is installed at the shrinkage section. The water flow speed at the shrinkage section is accelerated, and the pressure is reduced, resulting in the fertilizer liquid sucking people, and this fertilization method not only loses the water head in the throat section, but also is desirable only when the water pressure in the main pipe is not large.

Therefore, this fertilization method is also very limited in its use.

What I mean is that ordinary non-water-soluble fertilizer is the kind that happens to be sprinkled directly in the ground, for example, diammonium phosphorus has water-soluble diammonium phosphorus specially used for drip irrigation and ordinary diammonium phosphorus sprinkled directly in the ground, ordinary diammonium phosphorus poured into the fertilizer tank Xiaochang lead can be quickly dissolved after adding water, and then fertilize the crop through the pipeline, replacing water-soluble fertilizer with ordinary fertilizer is mainly to reduce costs, after all, a ton of water-soluble fertilizer is thousands more expensive than ordinary fertilizer.

General water-soluble fertilizer can not drip irrigation reason one, poor solubility, drip irrigation fertilization requires fertilizer solubility must be high, and seepage and is fully water-soluble without impurities precipitation, floating, etc., because the rigor of drip irrigation equipment determines the quality requirements of fertilizer slippery, if the application of general water-soluble fertilizer will block the drip irrigation head, resulting in the damage of the whole set of equipment can not be used normally.

Hello dear, happy to answer for you. It can be used for flushing. As the name suggests, drip irrigation fertilizer is poured into water and the operation is carried out at the same time.

From the perspective of fertilizer utilization, crops mainly rely on the root system to absorb nutrients, and the root hair area about one cm away from the root tip is the active area for nutrient absorption. Therefore, flush fertilization conforms to the principle of scientific fertilization, nutrients can be absorbed by crops through mass flow and diffusion, and can also prevent dry fertilizer from burning seedlings. Advantages of flushing drip fertilization:

Compared with pressure drip irrigation and furrow irrigation, the average water saving per mu is 150m3 mu, and the average water saving per mu is 200m3 mu compared with buried seepage irrigation and ditch irrigation.
