Shovel manufacturers introduce ginger planting techniques

Ginger has a long growth period and needs a lot of chemical fertilizer in the production process. When planting ginger, it is advisable to apply base fertilizer heavily, increase phosphorus and potassium fertilizer, and avoid excessive nitrogen fertilizer. Recently, some netizens who grow ginger asked the farmers: When do you need topdressing for growing ginger? How to plant ginger to supplement fertilizer? Here is a brief introduction of the shovel manufacturer for netizens' reference.

On the premise that sufficient base fertilizer is applied to ginger, the principle of topdressing is to use less and more fertilizer as far as possible, that is, the amount of topdressing each time should be less and the number of times should be more. Nitrogen, phosphorus and potassium should be used together, and ginger topdressing can be carried out in three times:

1. The first topdressing is usually carried out when the ginger seedling is about 30cm high and has 1-2 branches. Top dressing is mainly nitrogen fertilizer, 20 kg ammonium sulfate or diammonium phosphate can be applied per mu; If the sowing date is too early and the seedling stage is too long, the fertilizer can be applied for 2-3 times in combination with watering, with the same amount as above.

2. Generally speaking, the beginning of autumn is the turning point of ginger growth and nutrient absorption. After this period, plants grow faster, accumulate a lot of nutrients, and form product organs. The demand for fertilizer and water has increased. The second topdressing was carried out before and after the beginning of autumn in combination with the weeding of ginger fields. During topdressing, cake fertilizer or farmyard fertilizer shall be applied together with chemical fertilizer. Generally, 70 kg of cake fertilizer per mu, 1000 kg of decomposed chicken manure, 50~60 kg of compound fertilizer or 20 kg of urea, 30 kg of diammonium phosphate and 50 kg of potassium sulfate. The method is to open a fertilization ditch 15cm away from the base of ginger seedlings, sprinkle the fertilizer into the ditch, mix it with the soil, cover the ditch with soil, fill the soil, and finally water.

3. It usually takes place in the first ten days of September. When the ginger seedling has 6-8 branches and the rhizome expands rapidly, the third topdressing shall be conducted according to the plant growth. For ginger fields with high soil fertility and vigorous plant growth, less or no nitrogen fertilizer should be applied to prevent excessive growth of stems and leaves from affecting nutrient accumulation. For ginger fields with weak or general growth and low soil fertility, chemical fertilizer should be applied at this stage, generally 25~30 kg Hefei or 2.5 kg ammonium sulfate and 2.5 kg potassium sulfate per mu.
