High-yield cultivation techniques of Ginger

Ginger is an indispensable condiment in life, as the saying goes, "eat radish in winter and ginger in summer", which shows its position in life. There are many people who grow ginger, but few have a high yield. Let's take a look at the high-yield cultivation techniques of ginger.

I. the choice of soil

Ginger has a long growing period and high yield, so it needs a lot of fertilizer. Because the root system is underdeveloped, the number of roots is small, the distribution is shallow, and good soil environmental conditions are needed. "do not plant ginger in fertile fields", ginger fields should be turned 30 cm to 40 cm deep. At the same time, we must choose sunny days to cultivate, and strive to make the soil whitening and weathering, creating a loose and fertile environment conducive to root growth. After a deep turn, the car is opened, usually about 100 centimeters wide. In order to eliminate waterlogging in ginger field in time, the groove depth should be between 70 and 80 cm.

After leveling the ginger field, build a ditch, plant ginger in the ditch, and the soil is used for soil cultivation. Because the soil is high, the rhizome grows fat and the yield is high. Generally speaking, the ridge of ginger should be compacted to facilitate field operation and prevent Rain Water from collapsing. Generally speaking, the ridge of ginger should be compacted to facilitate field operation and avoid collapse of Rain Water.

II. Fertilization

1. Fertilization time: no matter what kind of cultivation method is used, when ginger has two larger lateral branches, the lateral branches are highly similar to the main stem (that is, three branches). After this period, the above ground and underground rhizomes have entered a period of exuberant growth. The main performance is to improve the growth rate. On the one hand, there are a large number of branches, and the number of leaves increases accordingly. On the other hand, the underground rhizome is also expanding rapidly, a large number of nutrients accumulate to form product organs, and there is a great demand for fertilizer and water.

In order to ensure the high yield of ginger, it should be fattened. At this time, fertilization is called "trigeminal fertilizer" or "turning fertilizer", which plays an important role in promoting the growth of hair and rhizome. According to different cultivation methods, fertilization time is generally appropriate from early July to early August. As long as the ginger reaches the standard of three stages, it should be fertilized. Generally speaking, the ceiling is earlier than the small arch shed, the small arch shed is earlier than the basement, the basement is earlier than the exposed ground, and the ginger shade is removed before fertilization.

two。 Fertilization method: during this period, the number of chemical fertilizers should be large, plus soil cultivation, plus the use of organic fertilizers and more durable fertilizers and available fertilizers, or the use of organic-inorganic compound fertilizers, apply organic fertilizers such as high-quality organic fertilizers per 667 square meters (80 to 120 kg), high-nitrogen and high-potassium high-quality compound fertilizers 100 to 120 kg; or 25% (12-4-9) 160-200 kg of organic-inorganic compound fertilizers.

According to the order of "small first and then big", that is, from July 5 to 20, 1 beat 3 of the total amount is applied, and then soil cultivation is carried out again; in the first 5 to 15 days of early autumn, then topdressing the remaining 2max 3, and soil cultivation is carried out once. At this time, topdressing and applying organic fertilizer can not only improve the soil, but also ensure that ginger does not lose fertilizer in the late growth stage.

3. Topdressing: in order to promote the growth and rhizome expansion of ginger, autumn should be "big topdressing". The fertilization standard is: rotten chicken manure 3000 kg, cake fertilizer 70-80 kg, ammonium sulfate 20 kg per mu (cake fertilizer can be replaced by cooked black beans or soybeans 75 kg, and ammonium sulfate can be replaced by urea). For the "diammonium" and urea plots that are fertilized, chicken manure can supplement irrigation water. When ginger seedlings have more than 6 branches, fattening again, ammonium sulfate (or urea) is applied to 20 kg, potassium sulfate is 10 kg, in order to prevent premature decay.

Third, watering

When ginger has a large number of branches and rhizomes, the amount of water required increases significantly. In order to meet the water demand during this period, water should be supplied in time according to weather conditions, but too much or too much watering can also lead to premature aging of decaying roots, stems and leaves. Therefore, it is generally watering every 4 to 6 days (ginger planted under fruit trees can be watered less or not according to specific conditions), in order to keep the soil moist.

Fourth, weeding

Ginger seedlings in the high temperature and rainy season, weeds are overgrown, long-term water and fertilizer conditions are good, the phenomenon of weeds is also very strong, if weeding is not timely, grass and ginger seedlings compete for fertilizer, water and sunshine, ginger seedlings are prone to underdevelopment. Therefore, it is necessary to carry out inter-tillage weeding in time to prevent premature senescence of ginger seedlings caused by weeds.

Fifth, cultivate the soil

The root growth of ginger needs dark and humid conditions. in order to prevent the rhizome from expanding and exposing the ground, soil cultivation must be carried out in time. In early autumn, the first soil cultivation was combined with weeding and "big topdressing". The soil behind the ditch was placed at the base of the plant, and the trench became a ridge, followed by watering for the second and third times of soil cultivation. The time interval of the two soil cultivation is 10 to 15 days, each time the soil is 5 to 6 centimeters, and the surface thickness of the ridge gradually expands, creating suitable conditions for the growth of the rhizome.

The cultivation of ginger is very simple, but if you want to have a high yield, you need to have certain planting techniques. I hope these high-yield techniques will make it easy for you to harvest a lot of ginger.
