The reasons for the lack of heart of the latest baby dishes and the countermeasures

Baby cabbage is a kind of Chinese cabbage, but nuclear Chinese cabbage wants to compare, it is an early-maturing variety, the whole growth cycle is much shorter than Chinese cabbage, generally 45-55 days can mature, so there are more growers. However, there is a phenomenon of not caring when planting, which makes farmers very sad. Let's take a look at what is going on.

1. Varieties are not good.

Many farmers do not consider the characteristics of the varieties when planting, blindly buy seeds, such as the introduction of late-maturing varieties suitable for planting in the south to the alpine areas for planting, which will lead to the phenomenon of not caring.

Countermeasures: for this situation, we must first understand the characteristics of the variety, in accordance with local conditions to select suitable for local planting varieties, so that its normal heart.

2. Temperature discomfort

Baby vegetables like a mild climate, and the suitable temperature for growth in the rosette period is between 17 and 22 degrees Celsius. at this time, if the temperature is too high, it will lead to its growth, which will delay or not, but during the heading period, if the temperature is too low and there is not enough accumulated temperature, the heart leaves will grow slowly and cannot be perched normally.

Countermeasures: when planting, we should consider the local climate and environment, and choose the right time to sow seeds, so as to ensure that the rosette temperature is suitable and the heart is normal. If it is planted in the greenhouse, the high temperature should strengthen ventilation, reduce the temperature of the greenhouse, and the low temperature should take good heat preservation measures.

3. Improper fertilization

The temperature is extremely high in summer, which is also a period of rapid growth of baby vegetables, while some farmers apply nitrogen fertilizer rather than pay attention to the application of other fertilizers in order to promote the growth of baby vegetables, resulting in futile growth, can not be wrapped or loose.

Prevention and control methods: during the period of the greatest demand for fertilizer during the baby vegetable heading period, nitrogen, phosphorus and potassium accounted for about 90% of the total fertilizer. It is necessary to increase the application of phosphorus and potassium fertilizer, control the amount of nitrogen fertilizer, inhibit plant growth, and promote its pelleting. In addition, many times of foliar fertilizer spraying should be carried out in the heading period, and the heart is tight during the period.

4. Lack of water

The summer is hot and hot, water evaporation is large, and baby vegetables need a lot of water for their growth, so if they are not watered in time, they will not be covered. But summer is also a rainy season, the humidity in the field is high, which will affect the normal growth of baby vegetables.

Countermeasures: watering should be uniform and adequate, but do not water too much at one time, small water should be watered frequently, it is appropriate to keep the soil moist, and drainage should be done in time after rain.

The above is the reason why the doll dish is not inclusive and the countermeasures are introduced. I hope it can help you. If you want to know more about it, please follow us.
