Root is the root and root is the foundation. The quality of vegetable roots determines the growth and development of vegetables, which determines the quality of vegetables, the level of yield, and the income of vegetable farmers.
Vegetable roots have three functions:
The first is absorption. Can absorb moisture and nutrients. Absorb moisture to meet the need for leaf transpiration and the need for results. Absorb nitrogen, phosphorus, potassium and trace elements to meet the various physiological needs of vegetable plants.
The second is support. Plays a supporting role, allowing the vegetable plants to stand in the soil, so that the upper stems and leaves and fruit can be dependent.
The third is synthesis. Roots synthesize many endogenous hormones to meet the physiological needs of vegetable growth.
So, can we maintain the root system of vegetable plants and grow the root system robustly?
1. Strengthen the maintenance of vegetable plant leaves
"By relying on leaves to support, leaves rely on root length." The roots and leaves of vegetables are interdependent, interdependent, mutually promoting and indispensable. During the daytime, the leaves of vegetable plants use sun light as a driving force to produce nutrients through photosynthesis. Some of these nutrients are transported down to the roots, and the roots are well maintained and the root system can grow and develop. Fertilizers applied to the ground, such as nitrogen, phosphorus, and potassium, cannot be rooted and can only be absorbed and utilized by the root system. They can then be transported to the stems, leaves, and fruits through the transport of tissue from vegetable plants, or they can be used in the photosynthetic system. Re-transform during the process. Therefore, it can be said that the fertilizer applied to the ground cannot be directly rooted, but the photosynthetic products made from photosynthetic leaves grow the root system, and the growth of the root promotes the absorption of the above-mentioned mineral nutrients.
In some places, vegetable growers often blindly knock out the leaves of the lower part of the vegetable plant. In addition, more often than not, they are destroyed at one time and have a great influence on the normal growth and results of the vegetables. For example, the first fruit of the tomato plant does not leave leaves up and down, resulting in the first panicle fruit expansion is very slow, and some also grow too long, but also cause root growth difficulties, even if the majority of the application of fertilizer will not be absorbed by the root system. Some vegetable farmers leave enough leaves for the tomatoes to directly light the leaves around the top of the ear, causing difficulty in the growth of this ear and daily burning in places with strong sunlight. Cucumbers need 16 - 20 better functional leaves to ensure normal plant growth and high yield and stable production, while some vegetable farmers blindly knock down the lower leaves, and some of the leaves are too weak, causing plant weakness and yield decline. Therefore, blindly hitting the leaves without reason is very harmful, especially the leaves of the lower part of the plants. These leaves are the source of organic nutrients and are used exclusively for the supply of these nutrients. In this regard, we must focus on the protection of the lower leaves, lighter when the leaves are hit, and do not play too much at one time.
At the same time, it is necessary to strengthen pruning management, ensure a reasonable plant type, improve the visibility of leaves, increase plant resistance, prevent diseases and insect pests, ensure leaf health, and normal photosynthesis; spray chitosan, salicylic acid, and other foliage fertilizers, and strengthen leaves. The activity of endoenzymes increases photosynthetic efficiency.
2. Create good conditions for utilizing root growth
One is that the soil should be fertile and airy. Less organic fertilizer, rely on a variety of fertilizers to produce vegetables, will make the physical and chemical properties of the soil worse, the roots are not easy to stretch, poor ventilation, especially the poor ventilation caused by water in winter will often lead to root rot.
Therefore, fertilizing the soil is the key to the production of vegetables. Fertilization should grasp three aspects.
First of all, organic fertilizer should be reused. The addition of chicken manure and other organic fertilizers is undoubtedly an important means to increase organic matter in the soil and improve soil structure. Generally, 10 to 15 squares of chicken manure per mu can be applied, and 10 tons of earth-fertilizer can also be added to the ground. The crop straw 50-60 square, in order to increase the content of organic matter in the soil, improve the structure of the soil pellets, improve the permeability of the soil.
Second, pay attention to scientific formula fertilization. For new vegetable plots and poor soil fertility, the lack of various nutrients, especially trace elements, must be supplemented in advance according to the needs of different vegetables for fertilizer, so as to avoid the emergence of vegetable deferritation symptoms. In the application of chicken manure and other organic fertilizer, with the application of compound fertilizer 80-100 kg, rich in trace elements of fertilizer 20-30 kg.
Again, it is necessary to add biological bacterial fertilizer. A large number of experiments have proved that biological bacterial fertilizer can significantly improve soil structure, increase soil fertility, and promote the growth of vegetable roots. Therefore, supplementing biological bacterial fertilizer is an important measure to enhance soil fertility and promote root growth. When the organic fertilizer is used, 200 kg of biological bacterial fertilizer can be applied at the same time. This will not only significantly improve the structure and physical and chemical properties of the soil, but also inhibit the occurrence of vegetable root diseases (especially for various soil-borne diseases), and increase the yield and income. Very obvious.
Second, the ground temperature should be suitable. Ground temperature will significantly affect the growth of the roots. The low temperature does not last long, and it often causes rot. If the temperature drop of vegetables due to the cold current is too large, the new leaves will often appear purple, which is the performance of phosphorus deficiency, but the root cause is that the ground temperature is too low. If this phenomenon occurs, the surface of the leaves needs to be sprayed with potassium dihydrogen phosphate to make up for phosphorus, and more importantly, the ground temperature should be raised as soon as possible.
