Two major methods, five major causes, and four major measures, all for crop rooting!

Now, most of the crops have been planted. Some of the crops are growing very well after field planting, and some died. What is going on? In fact, the reason is that the root system of the crop is not growing very well. Because just after field planting, it is a critical period for root growth.

The quality of the root system directly determines the growth, yield and quality of the crop. If the root system of the crop does not grow well at the beginning, then let alone the management of the later period. It is very important that new roots are constantly growing and maintained in a healthy state.

What should a good root system look like?

1. Judging from the color of the root system

First, the old root epidermis of the crop is relatively pure and complete.

Secondly, the new parts are white.

Finally, the secretions are milky white or nearly colorless and transparent.

Judging from the color, if the root system meets these three conditions, it is relatively normal and healthy.

2. Judging from the shape of the root

The root system of the crop grows from all directions, it has no fixed direction, and there is no primary and secondary direction, but there are exceptions. If the crop is affected by our planting method or the impact of flushing and fertilization, sometimes it will have more roots on one side, less roots on the other side, which is normal.

In general, the main root of the crop is tapered, and the fibrous root is umbrella-shaped:

The growth of roots is orderly, old then new.

What is the reason for the poor root growth?

As the greenhouse crops were planted, the spring crops were about to be planted. However, some transplanted crops gradually died, and the old roots did not continue to grow. Some transplanted crops did not even wait for new roots. What are the reasons for this series of root systems?

1. Incorrect field planting method leads to dead seedlings

Some growers plant more crops in the spring, and the planting time is more concentrated, which may cause some crops to be planted in an incorrect manner. In this way, the root system of the crops cannot be relaxed immediately after planting. It will lead the phenomenon of dead rotten seedlings.

For example, for eggplant, we can change the flat border cultivation to ridge planting, which can increase the permeability of the soil, which will correspondingly reduce the dead roots of crops.

2. The watering method is incorrect

After the crops have been planted, some growers are watering too frequently.

3. Fertilization causes root poisoning

If the fertilizer is fermented at a certain temperature, it will release some harmful substances, then it will cause plant root poisoning and directly cause dead seedlings of the crop. After 40 days, it will be terminated.

To solve the problem, first of all, fertilizer must be applied early, about 40 days before fleld planting, then irrigation after deep application.

4. Fertilizer is too concentrated, affecting root growth

When the amount of manure is relatively large, if using a rotary tiller to turn the ground, when the depth of tillage is shallow (not more than 20 cm), a large amount of fertilizer is concentrated in the soil layer of 0-20 cm on the surface, which will affect vegetable roots.

Because the fertilizer is too concentrated, after slowing the seedling water, the soil solution concentration in the soil layer is too high, and the root system will be separated in the high concentration soil solution (that is, the water in the root system will be lost), thus the lack of water eventually caused the root system to die.

Therefore, it is recommended that after the vegetable fertilizer is used, the depth of tillage can exceed 35 cm, which can not only ensure that the fertilizer is evenly distributed in the soil, but also break the plow layer (the depth of the soil layer is about 28 cm, because long-term no cultivation will cause the permeability of the soil is poor), reducing the harm of excessive concentration of fertilizers.

5. The soil is too sticky and not conducive to rooting

Although the greenhouse of cohesive soil has better fertilizer and water retention, the permeability of the soil is poor, making the root system unable to breathe, and it is not conducive to root growth. If the plant growth does not change much after fleld planting, but some died. It may be that the soil is heavy and sticky, causing the root system to fail to get out of the matrix.

How to promote root growth?

1. Control the amount of watering

As the old saying goes, "Dry for roots growth, wet for seedlings growth", we can promote rooting by properly controlling watering, so we must watering after planting, but we need to pay attention to it, not excessive. The specific watering volume should be based on the actual situation of the greenhouse.

2. Increase the application of phosphorus and potassium fertilizers

By adding phosphorus, it can not only promote the formation and growth of early roots, but also improve the plant's ability to adapt to external environmental conditions. However, because phosphorus is immovable in the soil, it is recommended that the fertilizer be used as a base fertilizer .

For example, some root-eating medicinal herbs, garlic, onions and other shallow root crops must be fully phosphated before planting, which can promote rooting and help absorb more nutrients in the soil.

In addition, the distribution of potassium in organs and tissues with active plant metabolism is relatively high, which has the functions of ensuring the smooth progress of various metabolic processes, promoting plant growth, resistance to diseases and insect pests, and resistance to lodging. Therefore, timely potassium supplementation can also promote root development.

3. Use functional fertilizer with rooting

All crops need to be rooted. When the crop itself cannot take root well, we need to apply some rooting fertilizers, such as rooting fertilizers containing amino acids, alginic acid, humic acid, and chitin.

But many rooting fertilizers on the market contain hormones. Although the effect will appear immediately after use, the excessive use of hormone rooting agents can easily inhibit root growth and also lead to imbalance of crop hormones. It will cause premature aging.

4. Condition the soil

It is recommended that you can apply some organic fertilizer, because organic fertilizer can increase the content of organic matter in the soil and improve soil permeability. When the content of organic matter in the soil is high and the soil is loose, the permeability of the soil will be better. That is naturally very Conducive to the development of the root system.

In addition, if conditions permit, we can apply some bacterial fertilizers when watering crops in the later period. The beneficial microorganisms in the bacterial fertilizers have the effect of improving the soil and improving soil permeability, and can also loosen the soil while propagating. It can also decompose the fixed nutrients in the soil, and also produce some substances that promote the growth of the root system, which are very beneficial to the growth of the root system.

Now, it is the critical moment for most crops to grow roots. We must not miss it. If the root system of the crops you planted is not good and there are dead seedlings and rotten crops, then you must take effective rooting measures. Apply some hormone-free rooting fertilizers combined with bacterial fertilizers, or supplement phosphorus and potassium elements, otherwise, your crops will be in trouble later.
