Now the most advanced ginger cultivation technology

The top dressing at the seedling stage was mainly light and light fertilizer; After the top dressing twice, the first time was from early June to early July, at this time is the long-term period of Sun Jiangwang, which is the peak period of ginger fertilizer absorption, 20 kg of compound fertilizer and 10 kg of urea per mu; The second time was in early September and early October, when the ginger tuber was rapidly expanding, and 30 kg of compound fertilizer and 10 kg of potassium chloride were applied per mu.

Proper shade covering. The high temperature and strong sunshine in summer are extremely unfavorable to the ginger summer, so it is necessary to do a good job of shading and covering. Crops such as corn and soybeans can be interplanted between the edges of the furrows or shaded by sheds. At the same time, straw is covered between the ginger rows to reduce ground radiation and increase soil moisture.

Moisture management. Ginger must be kept moist throughout the growth period, and it is required to irrigate "running horse water" during drought, and drain it in time when the furrow is waterlogged.

1. Ginger is a perennial herbaceous root plant of the ginger family, mostly cultivated annually, its root system is fine, the edible part is an underground fertilizer stem, growing in the soil, and there are "three taboos" in the ginger ground, that is, avoid making connections, avoid stagnant water, and avoid exposure to the sun. Therefore, ginger land should choose loam or sandy loam with deep tillage layer, loose soil layer, fertile soil and rich organic humus, and the high-yield land is best close to the water source in the shade field, which is high dry and sunny and has good drainage. When preparing the land, it is necessary to turn over the deep garden foot, crush the soil to white, increase the permeability of the soil, form a deep ditch with a width of 4-6 feet, and the furrow surface is slightly arched, and dig a drainage ditch around it.

Before planting, sufficient basal fertilizer should be applied, and 20-30 soil miscellaneous fertilizers such as rotting cow manure can be applied per mu

200-300 kg of plant ash, mixed with soil after application.

Ginger cultivation techniques

1. The choice of ginger, since ginger is propagated by rhizomes, ginger should be selected to be thick, light yellow in color, shiny, and without scars of diseases and insects.

2. Germination time, generally speaking, the south is more suitable for germination from January to April, and the north is suitable for germination in May.

3. Cut the ginger into cubes, after the germination, cut the ginger into certain pieces, and make sure that there are young shoots on each piece.

4. Plant ginger blocks, dig pits at a certain distance on the land, then water each pit with manure first, and then put the cut ginger pieces into the pit and cover it with soil.

During the growth period of ginger, weeding and fertilizer should be applied regularly, mainly organic fertilizer and compound fertilizer, and attention should be paid to keeping the soil moist and watering in time.

To grow ginger, you need to choose healthy, thick, and well-colored stems. 3. Fertilization: During the peak growth period of ginger, it is necessary to water diluted nitrogen, phosphorus and potassium element fertilizer.

4. Disease: Remove the infected ginger seedlings in time and spray them with bactericidal agents.

The planting time of ginger is generally selected in April and May of each year, but the planting time near the northwest region can be one month earlier, and the planting can start in March, otherwise the ripening time will be too late, which will have an adverse effect on the ginger harvest.

The ginger stems used for planting should be healthy, stout, and the ones with excellent color and luster, and the ginger blocks have a stronger growth ability with obvious bud points. In terms of soil, sandy loam soil with strong ventilation and drainage is used to disinfect and sterilize the soil once before planting to avoid pests and diseases in the soil.

Before growing and planting in the soil, organic fertilizer and decomposing fertilizer can be added to the soil as base fertilizer, and nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other elemental fertilizers are diluted and irrigated during the peak growth period of ginger. In rainy weather and low temperature weather, top dressing should not be used, and thick fertilizer, raw fertilizer and excess fertilizer can not be used.

For ginger, it is easy to cause ginger blast, rot disease, spot disease, etc., because of the problem of maintenance methods, and it is very contagious, once the signs of disease are found, it must be sprayed with appropriate concentration of agents in time, and it can also be sterilized with potassium permanganate, lime water, etc.
