1. Selection of fertilizer varieties: Fertilization with drip irrigation should also select suitable fertilizer types according to the demand for nutrients, such as strawberries and melons. In the middle and late growth stages, the plants must have certain vegetative growth potential and ensure Fruits and fruits have good quality. Generally, urea, potassium dihydrogen phosphate, etc. are used to provide a large number of elements. Water-soluble multi-effect silicon fertilizer, borax, manganese sulfate, zinc sulfate, etc. are selected to provide medium and trace elements. Among them, trace elements can also be directly used with nutritious foliar fertilizers, such as Xingxin Fertilizer. The specific fertilizer to be selected should be determined according to the base fertilizer and plant growth.
2. Formulation of fertilizer solution: The fertilizer solution can be formulated into two solutions of high concentration and low concentration according to the fertilization method. High concentration solution is to prepare urea, potassium dihydrogen phosphate, etc. into 5-10% aqueous solution, medium and trace elements are formulated into 1-2% aqueous solution; low concentration solution is to prepare urea, potassium dihydrogen phosphate, etc. into 0.5- 1% aqueous solution, medium and trace elements are formulated into 0.1-0.2% aqueous solution for direct application.
3. Fertilizer dosage and mixed use: urea is applied 3-4 kg per mu, and potassium dihydrogen phosphate is 1-2 kg per mu. These two fertilizers can also be mixed. Medium and trace elements Generally, each fertilizer should not exceed 1 kg in a season crop, and the field applied per year should not exceed 0.5 kg.
4. Fertilization method: When fertilizing with high concentration solution, it can be carried out simultaneously with irrigation, that is, open the pipette switch of the fertilizer applicator, so that the fertilizer liquid enters the hose with the water flow, the flow rate of the fertilizer liquid is controlled by the switch; when the fertilizer is directly fertilized with the low concentration solution Close the irrigation valve, open the switch of the fertilizer applicator, fix the filter to the bottom of the fertilizer container, and switch on the fertilizer to fertilize.
5. Matters needing attention: 1 The prepared fertilizer liquid should not contain solid sediment to prevent dripping hole blockage; 2 high-concentration fertilizer liquid flow should be well controlled, not too large, prevent excessive concentration from harming crop roots; 3 close the straw when fertilizing ends On the upper switch, open the valve and continue to fill for a few minutes to flush the residual fertilizer in the tube.
Sub-membrane fertilization technology using hose drip irrigation
Sub-membrane fertilization technology using hose drip irrigation With the expansion of facility cultivation area, plastic film mulching has become an important means to improve the ecological environment of crops. This technology objectively improves the temperature of the ground, maintains sensation, and reduces the effects of weeds, but it is inconvenient for fertigation. At present, some farmers have laid a film hose drip irrigation facility under the mulch and used it for irrigation during drought. This simple drip irrigation facility can also be used for top dressing in the middle and late seasons of crops, as follows:
