Learn these four tricks to easily prevent vegetable size seedlings
Lay the foundation of planting to avoid roots The main reason for the uneven size of the seedlings after planting is that the manure is not well-fertilized. After the planting, some of the seedlings are damaged, the growth is weak, and some of the seedlings grow normally, resulting in a large difference in size. It is the simplest and most effective measure to carry out the high temperature shack in the vegetable break period and to rot the manure. As long as the manure is cooked, the chances of emergence of large and small seedlings in the shed will be greatly reduced. In addition, we must also pay attention to avoid the influence of two factors such as excessive planting water and deep planting. The planting water is too large, which is the most influential factor after the seedlings are planted. After the end of the exchange, after the fertilization, tumbling, ridge and other operations, the soil is extremely loose and breathable, so the water consumption of the first water is often more than twice the daily, and the damage to the roots is great. When the temperature is high in summer and autumn, the water volume is controlled at 60%-80% of the normal water volume. After 1-2 days, the watering is gradually increased to ensure that the roots of the seedlings are not dehydrated or oxygen-deficient. Planting too deep is also an important factor affecting root growth. The roots of tomato, pepper, cucumber and other vegetables are shallowly distributed, all of which are aerobic. The planting is too deep, which makes the soil permeability greatly affected and the slow seedlings slow. Before and after planting, avoid planting water is too large, pay attention to shallow planting when planting, generally the seedling substrate can be exposed slightly, so as to promote the slow-release of seedlings after vegetable planting, improve disease resistance and reduce root disease. Size seedlings are separately planted Adjusting the growth period of the seedling stage should start from the time of planting. Whether it is the vegetable farmers' own seedlings or the seedlings from the nursery, the seedlings have different sizes, especially when they are raising their own seedlings. At this time, the vegetable farmers should flexibly adjust the planting method in combination with the actual situation in the shed to ensure that the seedlings in the shed are consistent. There are differences in temperature and lighting conditions in various places in the shed, especially in the deep winter season. Because of the large heat dissipation area, the front face of the shed is fast, and the temperature is lower, especially at night, the seedlings grow slowly; Only the top heats up, the heat loss is relatively slow, the temperature is higher, and the seedlings grow faster. Therefore, when planting, it should be separated according to the size of the seedlings. The whole seedlings are arranged in the front part of the shed, and the small seedlings are planted in the back of the shed, which can well adjust the overall growth of the seedlings and ensure that the flowering results are neat. Control and promote weak management Want to make the seedlings grow as consistent as possible, what measures should be taken to improve it? First of all, the weak seedlings pay attention to promote root promotion. The same seedlings are weak, and there must be some reasons. It is necessary to pay attention to check whether the weak seedlings are not watered enough or watering too much roots, whether there are root diseases, and take targeted measures to remedy the weak seedlings. At the same time, the weak seedlings first weaken the roots, the weak ones mostly have fewer roots, and the expansion range is limited. Therefore, the most effective way to promote the growth of weak seedlings is to promote the roots first. The vegetable grower can use 1000 times Apollo 963 chitin or Wojiafu alginic acid, and 1000 times of seedling stage fertilization. It is specially used to root the weak tree, promote the rapid growth of weak seedling roots, absorb more nutrients, and grow fast and robust. . Secondly, Wang Miao is properly controlled. Strong seedlings grow fast, occupying a large space for growth. In the shed where the problem of large and small seedlings is more obvious, it is necessary to pay attention to the control of Wangmiao. The vegetable grower can choose a small watering can, and use the 500-fold or 1500-fold spray to plant the stems, leaves and growth points of the plant, and properly control the growth of the plant, which is conducive to maintaining the balance of seedling growth in the field. Strengthen the adjustment of pruning For the tomato that has already blossomed, when the growth is still uneven, the vegetable grower can appropriately reduce the height of the strong tree by taking the lead and leaving the side branch. There are many advantages to plant head change. Reducing the height of the plant is only one aspect. In addition, it can promote the stalk more robust, promote flower bud differentiation, and improve the ability of subsequent flowering of the flower head. The germination ability of tomato side branches is strong. If it is not managed, the side branches grow even stronger than the main branches. Using this characteristic of tomato, the grower can remove the growth point of the plant when the 2 spikes appear in the tomato, leaving a side branch of the lower part of the second ear flower to continue the flowering result. For a place where a small number of dead trees appear in the shed, it is difficult to make the growth of the seedlings consistent. At this time, the growth space left behind the dead tree can be utilized by the method of leaving more side branches. That is to say, in the plants around the dead tree, a method similar to eggplant double-stalk pruning can be used, leaving two main branches.
