Beware of these two things
Many farmers grow large cabbage, which is a common problem. The same parcels, the same seeds, the well-carried and high-yielding cabbage that others have planted, either loosely or in the form of yellow leaves, rotten gangs, burning hearts, and weakness。
Most people feel at first hand that it is a problem with varieties, water or pests. In fact, 70 per cent of daejeon's production and quality are dependent on fertilizer management. Many farmers rely on experience alone to fatten, to see cabbage grow slowly, to catch fat when it rains, and to find no fixed standards, which is the main reason why cabbage does not grow well。
Growing large cabbage without sophisticated technology and with no frequency of operation can significantly increase the availability and productivity of cabbage by holding on to the two key points of fatting, and can be done directly by new farmers。
The first key point is to strictly control the fatting time of cabbage。
The whole growing cycle of cabbage is divided into three stages: shrunk season, lotus season and terminal season. The demand for fertilizer varies from one stage to another, with the wrong timing and no use in fertilization。
The cabbage is just up to the seed age of the seedlings, with small strains, shallow roots and weak capacity to absorb fertilizers. This phase does not require a lot of fat. In the event of frequent application of fertilisation and re-fertilization during the period of seedlings, and high soil fertilizer concentrations, the roots are burned directly, resulting in yellowing and rigidity of cabbage seedlings, which are not normally grown at a later stage. Shrimp periods only take place in small, low-sized plots。
The cabbage enters the lotus season, which is a critical period for long leaves and crowning, and which must be followed by fattening. Vegetables grow fast and require sufficient nutrients to build a skeleton. This stage is characterized by a shortage of fatty, a small number of cabbage leaves and thin leaves, which are difficult to cover at a later stage。
Cabbage enters the final season, which is the core stage of production formation and the most critical period for fatting. Many farmers are in error and feel that cabbage is starting to wrap up so they don't have to fertilizer. There is insufficient condensation in the condensation season, the cabbage is loose, empty and light, the harvest is followed by impatience to store, and the transport process is prone to decay. It is not too early or too late to catch up with the ball, which can lead to long beetlings, and it does not increase productivity。
We need to avoid extreme weather. When the soil is dry, fertilizer cannot be applied directly and when water is accumulated in rain, both periods of time lead to direct fertilizer and decay of the roots。
The second key point is the selection of fertilizer types and application of the application method。
Many farmers grow cabbage, using only single nitrogen fertilizer. A single nitrogen fertilizer will only allow cabbage to grow leaves and sprouts, and will not promote condensation. Long-term exposure to nitrogen fertilizers, high water content in cabbage blades, long planters, poor resistance, prone to disease, gang failure, heart burning, poor taste after harvest and shorter storage times。
Growing large cabbage to catch fat requires a phased mix of fertilizers. Lactation periods can complement the basic nutrients needed for plant growth, mainly with quick-impact fertilizer. The ball season focuses on supplementing potassium fat with a small amount of compound fat to meet the growing nutrient demand of cabbage and to keep it tight。
There's a standard way to get fat. The methods used by farmers to catch fertilizer are divided into flushing and denting. Large areas of daejeon are grown, priority being given to water-spraying, and nutrients are distributed evenly and do not cause local obesity. Small areas of vegetable gardening, which can be applied to caves, must be followed by fertilization。
After all the cabbage is fattening, it must be watered. The application of fertilizers to the soil requires hydrolysis in order to absorb the roots. Fertilizers are not watered and remain on the surface of the soil or in the shallow layers, not only unabsorbed, but also volatilized and prone to burning root cabbage。
Besides that, you have to avoid a few common fat-hunting mistakes。
No frequent pursuit of fattening, no daily fertilization for cabbage growth, and just according to the stage of growth, can result in soil sheeting and salt accumulation. Do not re-fertilize the cabbage in the later stages of its growth, which can easily lead to a cabbage cracker. The lack of long-term use of unperformed farm fats can cause pest problems and root burning。
In general, large cabbage is not difficult to fatten, is not subject to all kinds of new fertilizers and is not used frequently. As long as we are able to catch up with the growth stage of the fat, select the type of fertilizer and apply the method of application, and make a reasonable supplement to the diet of the cabbage, we can grow large cabbage with a tight heart, strong strength and steady yield, suitable for use by all open vegetable gardens and cabbage growers。
