Skillfully cultivate soil and ginger can steadily achieve high yield.

Soil cultivation is an important measure to determine the yield and quality of ginger. Only when the soil is cultivated properly can the ginger grow healthily and the yield is high. The rhizome of ginger needs to grow in a dark, moist environment and stop growing at the sight of light. Therefore, the soil should be cultivated with the growth of ginger. If the soil is not cultivated in time, the roots of ginger will be exposed to the air, which will seriously affect the quality and yield of ginger.

What methods should be mastered for Jiang Peitu? How to cultivate the soil can be more conducive to the expansion of the rhizome of ginger and increase the yield? Li Yonghui, an old ginger farmer from Xiaodalu Village, Linghe Town, Anqiu City, Shandong Province, summed up his experience of growing ginger for more than 10 years, and put forward a method of cultivating soil according to the needs of different customers: different customers have different consumer needs, and southern customers like slender "finger ginger". Then the soil needs to be thick, so as to promote the rhizome of ginger to grow upward faster and make the pieces of ginger slender. Northern customers and export ginger, mostly like short, thick pieces of ginger, then soil cultivation should grasp the principle of a small number of times, each time the soil should be less, should be shallow, in order to promote the root development of ginger.

For Jiang Peitu should be in line with local conditions, in line with the times, it is appropriate to cultivate the soil for 3 times.

For the first time, the rhizome of ginger had 3-5 bifurcations, but it began when it was not exposed to the surface, and the soil was about 2 cm thick. At this time, only need to use a small hoe or hooks and other agricultural tools, the ginger planting ditch on both sides of the 4cm wide ridge soil (generally ridge width 25cm 30cm) along the ridge edge to the planting ditch, watering. This can not only prevent the growth of weeds, but also conducive to the expansion of the rhizome of ginger. The first cultivation of soil should not be too thick, otherwise it will easily affect the air permeability of the soil, hinder the growth of new ginger buds, reduce the bifurcation of rhizome, grow slowly, and affect the yield and quality.

The second soil cultivation should be carried out 20 days after the first soil cultivation, and the soil thickness is 2cm. At this time, the ridge soil on both sides of the ginger planting ditch can be leveled into the ginger planting ditch with agricultural tools such as small hoes or hooks. This time, the soil should not be too thick, otherwise it is easy to cause difficulties in the growth of ginger roots and affect the yield.

The third soil cultivation, also known as "Dapei", was carried out 15 days after the second soil cultivation, with a thickness of 7cm and 8cm. At this time, it is necessary to cultivate all the soil on the original ridge into the planting ditch, so that the original ginger growth ditch becomes a ridge, and the original ridge becomes a ditch. This time, soil cultivation is very important, and it is the key to determine the growth and development of ginger rhizome. If the soil is shallow, the ginger is short and thick; if the soil is thick, the ginger is slender. Later, if ginger buds are found to be exposed, the soil should also be cultivated in time to ensure the normal growth of ginger rhizomes.

Every time to cultivate soil should be combined with fertilization, watering, should first fertilize and then cultivate the soil and then water. Before the first and second soil cultivation, 5 kg compound fertilizer and 40 kg bio-organic fertilizer can be applied per mu, about 15 cm away from the base of the plant, and the compound fertilizer should not be applied to the base of the plant to avoid burning seedlings. The last time to cultivate the soil should increase the amount of fertilizer, at this time is the period of the fastest growth and development of ginger rhizome, need a large amount of fertilizer, can apply 50 kg compound fertilizer and 75 kg bio-organic fertilizer per mu.
