This year's climate is different from previous years, so the soil-receiving phase requires more targeted operations and management and the time of cultivation will change. For example, the temperature difference between day and night is not conducive to the growth of ginger in the early stage of growth; high temperature and high humidity are not conducive to the growth of ginger in the middle and late stages, which leads to problems such as early onset and difficult prevention and treatment of "rotten neck" at this stage.

Ginger soil and topdressing depends on the growth of ginger. Generally, the standard for large-scale soil is: ginger is preferably 5-6 branches. If the soil is premature, the temperature difference between day and night is small and the high temperature is likely to cause the stems and leaves of the shoots to grow, and the nutrient accumulation of the roots is less developed. If the soil is too late to catch up with the rainy days, the ginger leaves are exposed to the ground and stop growing, which is not conducive to the growth and development of ginger roots.

First, why do you want to cultivate?

Soil cultivation can effectively improve the yield and quality of ginger. The roots of ginger stop growing when they see light, so they are suitable for growing in a dark, humid environment. Therefore, in the production, the growth of ginger must be carried out in time. If the soil is not timely, it will seriously affect the quality and yield of ginger.

Second, how to cultivate soil is more reasonable?

Ginger is cultivated three times for two times of small soil and once again.

1. The first time the soil was cultivated. The first time the soil is cultivated in the ginger growing to 4-5 branches. Note that the first time the soil should not be too thick, just divide the 4-5 cm wide ridge soil on both sides of the ginger planting ditch along the ridge to the planting ditch. Inside, cover the outcropped ginger pieces. Top dressing is required during the first soiling process to promote the growth of ginger.

2. The second time the soil is cultivated. After the first soil cultivation for half a month, the second cultivation was carried out, and the method of soil topdressing was the same as the first time.

Note that these two soils are called “small soil” in production. The soil should not be covered too thick twice, otherwise it will easily cause the growth of ginger sprouts to be blocked, the branching of roots and stems will be reduced, the growth will be slow, the yield and quality will be affected, and the thickness is generally 2-3 cm.

3. The third time the soil was cultivated. The third cultivation of soil is also called “large soil” in production. It is carried out after 5 months from the second small soil, and 5-6 branches of ginger seedlings. The large cultivating soil should be used to transplant all the soil on the original ridge into the planting ditch, so that the original ditch of ginger grows into a ridge and the ridge becomes a ditch. The soil is generally about 8 cm. The third cultivation is the key to determining the growth and development of ginger roots. If the soil is shallow, the ginger is short and thick; if the soil is thick, the ginger is thin and long. If it is found that there is ginger bud exposure, it should be cultivated in time to ensure the normal growth of the roots of ginger.

In the third soil-cultivating stage, appropriate topdressing can be carried out according to the previous two times of topdressing and topdressing. In principle, it is not recommended to apply compound fertilizer in this period, and organic fertilizer can be applied appropriately.

Third, the problem should be paid attention to the soil

1. After the soil is cultivated, ginger is prone to large-scale dry-yellow yellow leaves.

The main reason for dry-yellow yellow leaves is due to the use of a large amount of compound fertilizer or the use of unfertilized manure bean cakes. It is not recommended to use unfertilized manure, fertilizers such as bean cake, and reduce the use of compound fertilizer. And when using compound fertilizer, it needs to be applied at a distance of about 15 cm from the base of the plant. The compound fertilizer should not be applied directly to the base of the plant to avoid burning seedlings.

2. Due to improper man-made or mechanical operation during the process of soil cultivation, the root system of ginger is particularly likely to be damaged, which affects the growth of ginger in the later stage.

Therefore, it is necessary to carry out root maintenance in time after the soil is cultivated, so that the ginger root system can restore the absorption capacity as soon as possible. For the choice of root products, hormonal fertilizers must not be used, because such fertilizers can not only repair the root system well, but may increase the root damage. After each soil cultivation, it is recommended to use 2000ml of 963 roots to repair the injured roots as soon as possible to ensure the normal growth of ginger.

3. Prevention and control of pests and diseases during soil cultivation.

The third time to cultivate the soil to do the prevention of ecdysis, it is recommended to use 1.8% avermectin 2000-3000 ml with water, rotten neck (root rot) recommended to use 1 kg of tonic, methyl sulphur 600 grams of fungus is used for prevention and treatment, and white star disease is in a high incidence period after large soil cultivation. Therefore, it is necessary to use a fungicide such as azoxystrobin to prevent it in time.

4. Watering problems before and after soiling.

After 2 to 3 days of soiling, water is re-watered. If the soil is irrigated immediately after irrigation, it will cause root disease. Usually watering should be carried out reasonably. After the third soiling, the watering should be poured. At the same time, the dry and wet should be alternated reasonably so that the roots are not ventilated.

Fourth, after the management of large soils

Ginger grows three times after the soil is about to enter the stage of rapid growth of underground rhizomes. The management point of this stage is “removal of nutrients”. After the third cultivation, the ginger block is in a rapid expansion period, so the nutrient and water demand are high. It is necessary to supplement the nutrition through the top dressing of the ditch and promote the “nutrient transfer cultivation method”. After the third cultivation, the water can be applied with water to dissolve the fertilizer by 2 to 3 bags per acre, and the continuous application is 4 to 5 times. Ginger cultivated in the open air, two-meter membrane and four-meter membrane can be applied to water before the National Day. The cultivation of ginger in the large arch shed can be delayed until about 20 days before harvest, and the foliar fertilizer should be replenished in the middle and later stages.

In the process of ginger growth, each time the soil is essential, so the growers should pay more attention when planting. If the soil is improperly manipulated, it will easily cause losses such as production reduction.
