How is ginger high-yield cultivation? Ginger is an indispensable seasoning in many people's lives, and eating more ginger can drive moisture. As we all know, the growth of ginger in the seedling stage is long, and it is mainly to grasp the following major points after high yield.
1 Site preparation
Ginger has a long growth period, high yield, large amount of fertilizer, and because the root system is underdeveloped, the number of roots is small, and the distribution is shallow. Therefore, good soil environmental conditions are required, "not the fertilizer field does not plant ginger." Ginger ground should be deep 30~40 cm. At the same time, it is necessary to choose sunny days for ploughing, and strive to make the soil white and weathered, resulting in an environment that is loose, fertile and beneficial to root growth. After deep turning, open the car for squatting, the general width is about 100 cm. The trench should have a depth of 70~80 cm, so as to eliminate the ginger water stain in time.
After deep ploughing and ploughing, the ginger is planted in the ditch, and the ginger is planted in the ditch. The bauxite will be used for soil cultivation in the future. Because the soil is high, the rhizome grows fat and the yield is high. Generally, the scorpion is 33~40cm, the bottom of the ditch is 10~13cm wide, the bottom of the sill is 30~35cm wide, and the width of the sorghum is 15~20cm. The side of the wall is steep and the side is inclined. The ginger scorpion should be compacted so that Field operations and avoiding rainwater collapse.
2 Fertilization
Ginger has a long growth period and requires a large amount of fertilizer. It is a fertilizer-fertilizer crop. During the growth of ginger, the rhizome is gradually divided and expanded, and it is necessary to continuously absorb various mineral nutrients such as nitrogen, phosphorus, potassium, calcium and magnesium from the soil. Therefore, in addition to the application of base fertilizer, high-yield ginger must also be staged and topdressed to meet the demand for nutrients in the growth of ginger.
2.1 Fertilization time
Regardless of the cultivation method, when ginger has two large lateral branches, and the height of the lateral branches and the main stems are similar (ie, the three-stem period), the aboveground and underground rhizomes enter the vigorous growth period at the same time, mainly showing the growth rate. On the one hand, the number of leaves increased, and the number of leaves increased accordingly. On the other hand, the underground rhizomes also rapidly expanded, and accumulated a large amount of nutrients to form product organs, which required a large amount of fertilizer and water.
In order to ensure high yield of ginger, topdressing should be carried out. At this time, fertilization is called “three-fertilizer†or “transfer fertilizerâ€. This top dressing plays an important role in promoting hair growth and rhizome enlargement. Fertilization time is generally suitable according to the cultivation method from the beginning of July to the beginning of August. As long as the ginger reaches the three-pronged standard, it should be fertilized. Generally, the greenhouse is earlier than the small arch shed, the small arch shed is earlier than the mulch, and the mulch is earlier than the exposed ground. Remove ginger shaded grass before fertilizing.
2.2 Fertilization method
In this period, the amount of topdressing should be large, combined with the cultivation of soil, combined with the application of long-lasting organic fertilizer and quick-acting fertilizer, or the application of organic-inorganic compound fertilizer alone. The total application amount is 80-120 kg per 667 m 2 with high-quality organic fertilizer (such as Cailun Zhongke and other organic fertilizers), and 100-120 kg with high-nitrogen and high-potassium high-quality compound fertilizer; or 25% (12-4-9) organic Inorganic compound fertilizer 160 ~ 200 kg.
According to the order of “Xian Xiao Pei and Da Da Peiâ€, it is roughly 1/3 of the total amount applied in July 5-20, and a small soil is cultivated; the remaining 2/3 is applied 5 to 15 days before the beginning of autumn. , carry out a large earth. At this time, the fertilizer is applied to increase the organic fertilizer, which not only improves the soil, but also ensures that the ginger does not lose fertilizer in the later stage of growth.
2.3 sufficient topdressing
In order to promote the growth of ginger and roots, a "big top dressing" should be carried out in autumn. The standard of fertilization is: 3000 kg of decomposed chicken manure, 70-80 kg of cake fertilizer, 20 kg of ammonium sulfate (the cake fertilizer can be replaced by 75 kg of cooked black beans or soybeans, and ammonium sulfate can be replaced by urea). For plots that have been applied to “diammonium†and urea, chicken manure can be supplemented with irrigation. When there are more than 6 branches in Jiangmiao, another top dressing is applied. 20 kg of ammonium sulfate (or urea) and 10 kg of potassium sulfate are applied to prevent premature aging.
3 see the sky watering
When a large number of ginger branches and rhizome enlargement, the water requirement is significantly increased. In order to meet the moisture requirements of this period, water should be timely watered according to the weather conditions. However, if the watering is too frequent, it will also cause rotten roots and premature senescence of stems and leaves. Therefore, water is usually poured every 4 to 6 days (the ginger planted under the fruit trees, depending on the specific situation, less watering or no watering), in order to keep the soil moist.
4 timely weeding
The seedling stage of ginger is in the hot and rainy season, and the weeds are abundant; the long-term water and fertilizer conditions are good, and the weeds are strong. If the weeding is not timely, the grass and the ginger seedlings compete for fertilizer, fight for water, and fight for the sun. Therefore, it is necessary to carry out cultivating and weeding in time to prevent premature senescence of plants.
5 timely soil
The roots of ginger grow in dark and moist conditions. In order to prevent the roots from expanding and revealing the ground, it is necessary to carry out the soil in time. In the early autumn, combined with weeding and "large topdressing" for the first time, the soil on the back of the ditch was changed to the ridge at the base of the plant; the second and third soils were later combined with watering. The time interval between the two soils is 10 to 15 days, and each time the soil is 5-6 cm, the ridge surface is gradually thickened and widened to create suitable conditions for the growth of the rhizome.
6 Foliar spray fertilizer
In the middle and late stages of ginger growth, foliar spray can be applied with chemical fertilizer, vegetable special fertilizer and urea aqueous solution to prolong the photosynthesis time of leaves, improve photosynthesis efficiency, promote plant growth and development, and prevent premature senescence of leaves. Especially for poorly grown ginger seedlings (including weak seedlings and yellowing ginger seedlings), foliar spray fertilizer can be applied early and the number of spray fertilizers increased.
7 lightly grow ginger
According to the market conditions, the ginger can be harvested in the long-term harvest of ginger (also known as "扒è€å§œ"). The method is: open the soil layer along the direction of sowing, revealing the ginger, the left hand holding the stem of the ginger seedling, the right hand Ginger is planted to separate it from the plant. Be careful not to shake the ginger seedlings to prevent premature aging of the roots, and seal the ditch in time after removing the ginger. It is not advisable to take ginger for weak ginger seedlings to avoid premature aging.
8 shed protection
In order to ensure the high yield of ginger, the sheds should be planted before the first frost to prolong the growth time (according to relevant experts' research and practical experience, each time the ginger harvest is delayed by 1 day, the yield per acre can be increased by 50 kg). The temperature of the arch shed is controlled at 25 °C ~ 28 °C during the day and 15 °C ~ 18 °C at night. Generally do not water, but pay attention to the release of wind to prevent harmful gas damage. In this way, the growth period of ginger can be extended by about 20 days.
