What are the methods of using trace element water soluble fertilizers

1) Soil fertilization.

That is, trace elements are used as base fertilizer, seed fertilizer or top dressing.

Fertilizer is applied to the soil. Although the utilization rate of fertilizer is low, this application has a certain after-effect. This fertilization method is often used for industrial wastes containing trace elements and slow-acting micro-fertilizers. (2) Seed treatment.

It is divided into two methods: soaking and dressing. When soaking seeds, the seeds are immersed in a trace element solution, the seeds absorb the solution and swell, and the fertilizer enters with water. The commonly used concentration is that the time is 12-24 hours.

Seed dressing is to dissolve the trace element fertilizer with a small amount of water, spray the solution on the seeds, stir evenly, so that the seeds are stained with the solution and then dry and sow, generally 2 6 grams of fertilizer per kilogram of seeds.

3) Root topdressing.

That is, the trace element fertilizer solution is sprayed on the plant with a sprayer, and the solution concentration is commonly used to operate into the plant through foliar or stomatal absorption.

Be. 4) Dip the seedlings in the roots.

This is a special fertilization method for rice, and other crops that need to be transplanted can also be fertilized by dipping the roots of the seedlings.

There are many ways to use trace elements? There are a few that you can briefly introduce!

1. Drip irrigation, sprinkler irrigation. In desert areas or places where water is extremely scarce, as well as large-scale farms and high-quality and high-value-added cash crop plantations, fertilizer is dissolved in water during irrigation, and the process of fertilization is also the process of spraying dripping water. At this time, the nutrients needed by plants can be obtained through water-soluble fertilizers, which not only save water, fertilizer, but also save labor.

Water-soluble fertilizers should be used in small quantities and many times when used for drip irrigation: reduce leaching losses caused by large amounts of fertilizer at one time. Fertile leaf water-soluble fertilizer is 2-3kg per mu each time. When fertilizing with drip irrigation, drip water first, and start fertilizing after the pipe is filled with water.

In principle, the longer the fertilization time, the better, but if it coincides with the rainy season or the current rainfall is large, the dripping time should be appropriately shortened. Immediately after the end of fertilization, drip water for 20 to 30 minutes to drain all the residual fertilizer in the pipe. If the tube is not washed, lower plants or microorganisms such as moss and algae may grow at the dripper and clog the dripper.

Sprinkler irrigation and micro sprinkler fertilization, if the concentration of fertilizer solution is too high, it is easy to burn leaves.

2. Soil irrigation. When the soil is watered or irrigated, it is mixed in the irrigation water first, so that the roots of the plant can be fully exposed to the fertilizer, and the chemical nutrients are transported to the various tissues of the plant through the respiration crops of the roots.

3. Foliar fertilization. Foliar spraying can greatly improve the absorption and utilization efficiency of fertilizer by diluting fertilized leaf trace element fertilizer, boron fertilizer or zinc fertilizer according to 1500 times of solution, or dissolving it in water with non-alkaline pesticides (most of the commonly used pesticides are non-alkaline). For foliar sprays, dilute 1000-1500 times.

Spray once every 10-15 days during each growth period of the crop, a total of 2 3 times. There is no need to respray in case of rain.

At present, the more common medium and trace element fertilizers include iron fertilizer, boron fertilizer, zinc fertilizer, manganese fertilizer, copper fertilizer, molybdenum fertilizer, etc., most of which are soluble compounds. Different regions and different crops use different medium and trace element fertilizers, but generally have a significant yield increase effect, generally up to 5%-50%. The application of medium and micro fertilizers mainly improves the inorganic nutrient balance of crops.

1. What are the medium and trace element fertilizers?

1. At present, the more common medium and trace element fertilizers include iron fertilizer, boron fertilizer, zinc fertilizer, manganese fertilizer, copper fertilizer, molybdenum fertilizer, etc., most of these fertilizers are soluble compounds, and are necessary trace elements in the process of crop growth and development, but because the demand of crops for these elements is particularly small, it is called trace elements.

2. The medium and trace element fertilizers applied in different regions and different crops will be different, but there will generally be a very obvious yield increase effect after use, which can generally reach 5%-50%, especially the effect of medium and low yield fields will be more obvious. In some areas with serious deficiency of medium and trace elements, if targeted use of medium and trace element fertilizers on fruit trees and vegetables, the yield of crops will be greatly increased.

3, the application of trace element fertilizer, mainly to improve the inorganic nutrient balance of crops, trace element fertilizer can not only greatly increase the yield of crops, but also improve the quality of agricultural products, for cotton, kenaf and other economic crops, increase the application of trace element fertilizer can also enhance the strength of fiber.

Second, how to use medium element water-soluble fertilizer

1. Methods such as flushing, topdressing, drip irrigation and spraying can be used, if the method of flushing is used, 8-15 kg per mu is used each time, and 800-1000 times of liquid is sprayed on the foliar surface; If drip irrigation and sprinkler irrigation are used, it is recommended to dilute the fertilizer 300-500 times before application, and the specific application rate and application coefficient must be determined according to different soils and different crops.

2. The water-soluble medium element fertilizer can be used with a large number of element fertilizers, which can make up for the physiological diseases caused by the lack of medium elements in the crop, and make the crops absorb more comprehensive nutrients, so the medium element is the best partner of a large number of elements.

3. If only nitrogen, phosphorus and potassium are applied to crops, they cannot play a role in comprehensively supplementing nutrition, and must be used with calcium, magnesium and other medium elements to achieve the purpose of high quality and high yield of crops. The application of medium element water-soluble fertilizer to soil can improve the utilization efficiency of nitrogen, phosphorus and potassium in soil.
