At this stage, the earlier-growing ginger is undergoing large earth-cultivation or is about to carry out large-scale cultivation. The ginger that grows later is also under cultivation.
Overall, it is the golden stage of ginger cultivation.
However, why do we need to cultivate earth? How to make soil more conducive to high yield and quality? What issues do you have to pay attention to?
What you think is not necessarily correct
You may think that I have planted my ginger for the rest of my life. I can't understand the soil. Is soil fertilization not covered soil? What's worth noting is that this is what I do every year and I don't feel anything wrong with it.
However, what you take for granted is not always correct.
The fact is this drop
First of all, you have been planting ginger for many years. If you cultivate soil every year, you need to think about it. Every year, the climate is different, for example, this year's climate is more unusual. The temperature difference between day and night in the early growth period of ginger is not good for the growth of ginger seedlings; the high temperature and humidity in the middle and late period is not conducive to the growth of ginger, which leads to the occurrence of "bad neck" at this stage. Early, difficult to prevent and other issues.
Under such environmental conditions, the growth of ginger is bound to be different from previous years. Therefore, the corresponding cultivation phase requires more targeted operations and management.
Secondly, the annual growth of ginger will not be exactly the same due to various reasons, and there must also be differences in the timing of soil cultivation.
Therefore, ginger top-dressing can not be determined based on the previous years, but should be based on the growth situation of their own ginger, flexible control. Generally speaking, the standard for large soils is that ginger grows to 5-6 branches.
Because the temperature is high and the temperature difference between day and night is small, it is easy to cause long stems and leaves in the shoots, less accumulation of nutrients in roots and slow development. When the soil is too late, it is catching up with the rainy days. As a result, ginger slices are exposed on the ground and they stop growing due to light. This is also not conducive to the growth and development of their rhizomes.
Finally, after clearly defining the time of operation and management and earth-cultivation, there is also a large gap between details of soil cultivation and fertilization.
If some users cultivate soil after the completion of soil, large areas of yellow leaves, seriously affecting the growth of ginger; some users cultivate soil after a long period of time, no growth of ginger and so on. These are the impaired growth of ginger caused by improper fertilization, improper operation, and improper management during the earth-cultivation stage, which ultimately affects the quality and yield of ginger.
After understanding the basic facts of the above-mentioned ginger cultivation stage, Xiaobian will give you the basic content of the ginger cultivation stage, and hopes to help your ginger management.
Why do you want to earth?
Soil cultivation is an important measure to increase the yield and quality of ginger.
Ginger's rhizomes are suitable for growing in a dark, moist environment that stops growing when light is seen. Therefore, the production must be performed in time with the growth of ginger. If the soil is not timely, the rhizome of ginger will be exposed to the air, which will seriously affect the quality and yield of ginger.
How to earth more reasonable?
The soil is generally divided into three times, that is, two times of small earth and one large earth.
The first earth.
In time, it takes about 4-5 branches to grow ginger. This time, it is not easy to make the soil too thick. Just 4-5 cm wide ridges on both sides of the ginger planting ditch are scribed along the edge of the ridge to the planting ditch. , cover the exposed ginger block can be.
During the process of earth-cultivation, it is necessary to carry out top-dressing. It is recommended that 400 mu of organic fertilizer and 50 kg of compound fertilizer be used per mu.
The second time earth.
About half a month before the first earthing, the cultivation method was the same as the first time.
Note: These two soils are called "small earths" in production. Do not cover too thick twice in the soil, otherwise it will easily cause the growth of ginger sprouts to be impeded, the rhizomes will be reduced, the growth will be slow, and the yield and quality will be affected. The thickness is generally 2-3 cm.
The third earth training.
It is also known as "large soil" in production. Generally, after the second half-cultivation, ginger seedlings have 5-6 branches.
This time, all the soil on the original ridge was cultivated in the planting ditch, so that the ditch where the original ginger grew became a ridge, and the original ridge became a ditch. The earth usually covers about 8 cm.
It is very important to cultivate soil this time. It is the key to the growth and development of ginger.
If the soil is shallow, the ginger block will be short and thick; if the soil is thick, the ginger block will be thin and long. Later, if ginger buds are found, soil should be cultivated in time to ensure normal growth of ginger roots.
In the period of large earth-cultivation, suitable top-dressing can be carried out according to the top two top-dressing conditions. In principle, it is not recommended to apply compound fertilizer again in this period. Appropriate application of organic fertilizers, such as 300 kg of smart brand organic fertilizer, can be applied.
The problem that should be paid attention to
1. After soil is cultivated, ginger is prone to a large area of ​​dry yellow leaves.
After analysis, it is not difficult to find that the most important reason is due to the use of a large amount of compound fertilizer or the use of unfermented manure such as bean cake.
Therefore, for these problems, it is recommended that you must not use unfamiliar manure, bean cake and other fertilizers, while reducing the use of compound fertilizers.
Special attention should be paid to the fact that, when using compound fertilizer, it is necessary to apply 15 cm from the base of the plant to the ditch. The compound fertilizer should not be applied directly to the base of the plant to avoid burning seedlings.
2. Due to human or mechanical mishandling in the process of earth-cultivation, it is particularly prone to damage to the root system of ginger and affect the growth of late ginger.
Therefore, after the soil is cultivated, the root system must be maintained in time to allow the ginger root system to restore its absorption capacity as soon as possible. For the selection of root-raising products, hormonal fertilizers must not be used, because such fertilizers not only do not repair the root system well, but may increase the damage to the root system.
After each earthing, it is recommended to use 2000 ml of 963 roots to repair damaged roots as soon as possible to ensure normal growth of ginger.
3, during the cultivation of soil and pest control.
Before the soil is cultivated, the prevention of fleas must be done. It is recommended to use 1.8% of avermectin in 2000-3000 ml of water per osmotic device. The rotten neck (root rot) is recommended to use 1 metric ton of Don and methyl sulfide. 600 grams of mycotoxin are used for prophylaxis and prevention of leukoplakia after large earthworms. It is recommended to use azoxystrobin and other fungicides for timely prevention.
4. Watering problems before and after earthing.
The soil should be watered for 2 to 3 days. Do not irrigate as soon as possible, otherwise it may cause root diseases. Reasonable watering, especially after the large earth soil watering, but also to do a reasonable alternating wet and dry, so that the root system does not breathe oxygen.
After the big earth management points
After three times of earth-cultivation, the growth of ginger will soon enter the stage of rapid growth of underground rhizomes. The management points for this period are summarized in four words: "Nutritional Backward Movement."
That is, after the big earth, it is a period of rapid expansion of ginger, requiring more nutrients and more water. It is necessary to supplement nutrients by topdressing with gully, and implement the “Nutrient rearward cultivation methodâ€.
After the soil is cultivated, it can be used with water, irrigation, intelligent and fruit-blue special water-soluble fertilizer for 2 to 3 bags per mu, and continuous flushing for 4 to 5 times. Ginger cultivated in the open air, two-meter film and four-meter film can be used to infuse smart fruit and blue special water soluble fertilizer before the National Day. Ginger grown in the big arch shed can be delayed until about 20 days before harvest, and the leaves should be replenished in time. fat.
