Top dressing at seedling stage is mainly light and light fertilizer; After that, topdressing was carried out twice. The first time is from early June to early July. At this time, it is the long period of the sun, which is the peak period for ginger to absorb fertilizer. Topdressing 20 kg of compound fertilizer and 0/0 kg of urea/kloc per mu. The second time is from early September of 10 to early October of 10. At this time, ginger tubers expanded rapidly, and 30 kg of compound fertilizer and potassium chloride 10 kg were applied per mu.

Proper shading and covering. High temperature and strong sunshine in summer are extremely unfavorable to ginger in summer, so shading and covering are needed. Crops such as corn and soybean can be interplanted in the border or shed for shade. At the same time, straw is covered between ginger rows to reduce ground radiation and increase soil moisture.

Water resources management. Ginger must keep the soil moist during the whole growth period, and it is required to use "fast horse water" for irrigation during drought, and to drain water in time when water accumulates in furrows.

Extended data

Keep the fields free of weeds and loose soil. Use butachlor, herbicide diethyl ether, etc. Weeding after sowing and before germination of ginger seeds. Because ginger needs a lot of fertilizer in the growth process, it needs to be fertilized many times besides applying base fertilizer again.

Generally, after corn seedlings are fully sown 10 days or so, when the height of the seedlings is 2-3 inches, apply seedling-promoting fertilizer, and apply urea 10 kg per mu; After application, cover the border with soil to keep the soil moist, and combine intertillage weeding to cultivate the soil. Ginger is a potassium-loving crop, which is sensitive to the effect of potassium fertilizer, so it is necessary to apply more organic fertilizer and more quick-acting potassium fertilizer.
