The demand for nutrients in different growth periods of ginger is also different, the fertilization of ginger is mainly divided into the base fertilizer and fertilizer, in the planting of the base fertilizer can be applied to cake fertilizer, chemical fertilizer, organic fertilizer, fertilizer can be applied to urea, zinc fertilizer, boron fertilizer, potassium sulphate, diammonium phosphate and other fertilizers in the growth process.

1, base fertilizer

Organic fertilizer before planting can be combined with the ground scattering, per acre can be applied to high-quality rotted chicken manure 5-8 square, rotary tillage should be carried out after the fertilizer, cake fertilizer, chemical fertilizer can be focused on furrow, can be crushed before planting cake fertilizer, fertilizer focused on applying ditch, per acre can be applied to the cake fertilizer 150-200 pounds of nitrogen, phosphorus, potassium composite fertilizer 100 pounds, or urea, potassium sulfate, Calcium superphosphate 50 pounds each.

2, chase seedling fertilizer

plant growth during the seedling period is relatively small, so the amount of fertilizer is not much, but the seedling growth period is relatively long, in order to promote the growth of seedlings, you can choose in the seedling to 30cm high, with 1-2 branches for fertilizer, per mu can be used ammonium sulphate or diammonium phosphate 40 pounds, if planting time is relatively early, the seedling period will be relatively long, which can be used with the Watering for 2-3 times fertilizer, fertilizer dosage and the same as before.

3, chase turn fertilizer

Autumn before and after the plant growth is more rapid, and will be a large number of accumulation of nutrients and the formation of product organs, so the demand for fertilizer is also relatively large, in order to promote the high quality of ginger and high yield, this time can be combined with the ginger field weed control, the second chase fertilizer, is conducive to promote the development of the plant and the expansion of rhizomes.

Cake fertilizer or farmyard manure can be combined with fast-acting fertilizers, 140-160 pounds of crushed cake fertilizer per acre, 3-4 square of rotted chicken manure, 100-200 pounds of compound fertilizers or 40 pounds of urea, 60 pounds of diammonium phosphate, 100 pounds of potassium sulfate.

Open 1 fertilizer ditch in the side of the ginger seedlings 15cm from the base of the plant, sprinkle the fertilizer into the ditch and mix it evenly with the soil, then cover the soil to seal the ditch, cultivate the soil and then water thoroughly.

4, chase strong ginger fertilizer

(1) in early September, when the ginger seedlings have 6-8 branches, also belongs to the rhizome rapid expansion period, this time according to the plant growth for the 3rd fertilizer, for the growth of the weaker ginger field, as well as the low soil fertility of the ginger field, can be applied to the fast-acting fertilizers, especially potash, nitrogen fertilizers, so as to ensure that the nutrients required by the rhizome, per acre of fertilizer 50-60 kg. Compound fertilizer 50-60 jin, or ammonium sulfate, potassium sulfate 5 jin each, for high soil fertility, plant growth is more vigorous ginger field, you can choose to apply less nitrogen fertilizer, to avoid stem and leaf futile and affect the accumulation of nutrients.

(2) boron and zinc fertilizer can be used as a base fertilizer or extra-root fertilizer, zinc, boron deficiency in the ginger field as a base fertilizer, per acre can be applied 1-2 pounds of borax, 2-4 pounds of zinc sulfate, and fine soil or organic fertilizers evenly mixed, and then applied to planting furrows, as a follow-up and foliar spraying, per acre of available 0.05%-0.1% borax 50-70 liters, were selected in the seedling period, the hair of the planting period, Rootstock expansion period spraying 3 times.

Expanded:

Ginger is suitable for growing in a moist environment, breeding should be watered once a week to keep the soil moist, but higher temperatures in summer, water evaporation faster, this time to increase the number of times of watering, and ventilation for the ginger, to avoid the environment is too wet, resulting in the growth of ginger poor.

Ginger in the process of growth, easy to appear pests and diseases phenomenon, breeding should be in the disease-prone summer for the ginger spray sterilization agent, eliminate the bacteria on the plant, if you find that there is a ginger leaves appear yellow and dry phenomenon, to cut off the diseased leaves in a timely manner, to avoid infection of other healthy plants.
