How much is the price of kidney beans now? What fertilizer is best? scientific fertilization techniques

Kidney bean is a kind of edible legume. The scientific name is kidney bean, commonly known as two kidney beans or four kidney beans. Young pods or seeds can be used as fresh vegetables, can also be processed for canning, pickling, freezing and drying. So how much is the kidney bean price per jin now? What kind of fertilizer is the best? What are the scientific fertilization techniques?

What fertilizer is the best for kidney beans?

About 1500 kg of agricultural fertilizer is applied per mu, and 40-50 kg of compound fertilizer (30 kg of phosphate fertilizer and 10-15 kg of potash fertilizer) is used as base fertilizer. Topdressing should be applied twice at the initial flowering stage and podding stage, 10-15 kg per mu each time.

What are the scientific fertilization techniques for kidney beans?

(1) characteristics of fertilizer requirement

After kidney bean emergence, the root system begins to absorb various nutrients from the soil. With the growth of the plant, the nutrient uptake gradually increased and stored in the stems and leaves, and reached the maximum when it blossomed and fruited. At the extension stage of the pod, the nutrients stored in the stems and leaves are quickly transferred to the pod for its growth needs. Potassium is the most absorbed element from soil, followed by nitrogen, phosphorus, calcium, boron and so on. Although the plant needs more nitrogen, it can be fixed by rhizobium to meet the growth needs after root nodule formation, and there is no need to apply a large amount of nitrogen fertilizer in production.

(2) fertilization technology

Kidney bean needs medium fertilizer. According to the characteristics of needs, reasonable fertilization techniques are as follows:

1. The principle of fertilization in the production of kidney bean, aiming at the problems that most farmers do not have a good understanding of scientific fertilization, insufficient application rate of organic fertilizer, what kind of fertilizer they apply, and unreasonable fertilizer ratio, the following fertilization principles are put forward.

(1) giving priority to base fertilizer and supplemented by topdressing

(2) combination of organic fertilizer and inorganic fertilizer

(3) increase the application of organic fertilizer.

(4) rational ratio of nitrogen, phosphorus and potassium.

(5) supplementation of trace elements such as molybdenum, zinc and boron

2. Fertilization suggestion

According to the results of "3414" fertilizer experiment and large-scale demonstration and extension of kidney bean, the fertilization suggestions are as follows:

The main results are as follows: (1) the target yield is 2500-3000kg/hm2, organic fertilizer 35000-40000 kg, nitrogen fertilizer (N) 30-40kg, phosphate fertilizer (P2O5) 75~85kg, potassium fertilizer (K2O) 40~50kg and appropriate micro-fertilizer.

(2) the target yield is 2000-2500kg/hm2, organic fertilizer 30000-35000 kg, nitrogen fertilizer (N) 20-30kg, phosphate fertilizer (P2O5) 65~75kg, potassium fertilizer (K2O) 30~40kg and appropriate micro-fertilizer.

Special attention should be paid to: first, if you apply compound (mixed) fertilizer, you can only use potassium sulfate compound (mixed) fertilizer, because kidney beans have poor tolerance to chloride ion, and the application of common compound (mixed) fertilizer affects growth; second, potash fertilizer should not be applied in large quantities, otherwise the grain is easy to harden, affecting edible quality and commercial value.

3. According to the characteristics of different fertilizers and the characteristics of kidney bean, different fertilizers have different application methods.

The main results are as follows: (1) Organic fertilizer can be used as base fertilizer in planting pond, and it can also be used as pond cover fertilizer.

(2) when the soil fertility of nitrogen fertilizer is above medium, seed fertilizer is not applied, but all is topdressing, which can be applied at budding stage and podding stage as appropriate.

(3) concentrated application of phosphate fertilizer in planting ponds as seed fertilizer.

(4) 50% of potash fertilizer was applied as seed fertilizer and 50% was applied at budding stage.

(5) from the early flowering stage to the podding stage, trace fertilizer was foliar sprayed with 0.2-0.3% potassium dihydrogen phosphate and 0.2% borax solution, and continuously sprayed 2-3 times every 7-10 days. Molybdenum fertilizer is used as seed fertilizer and used as seed dressing.
