Cauliflower planting steps, how to cultivate seedlings, after planting, rationally irrigate

With the continuous development and improvement of greenhouse technology, greenhouse planting is accepted and adopted by more and more people. Especially the demand for vegetables is huge. Natural planting restricted by seasons and weather cannot meet the needs of the market. More and more growers are turning to greenhouses to produce vegetables, and the most sought-after vegetables must have the name of cauliflower. The market promotes production, and growers tend to plant cauliflower when they grow vegetables.

However, incorrect planting methods will not only not bring high economic benefits to the growers, but also make the growers pay for the cost of investment. Then, how to plant can effectively avoid losses and increase planting yield has become a matter of close concern to growers. . Sowing seeds directly into the soil is inconvenient for the management of cauliflower seeds and seedlings. The planting of cauliflower generally involves sowing the seeds in a concentrated place first. Wait until the seeds germinate and grow seedlings before transplanting them into the prepared soil. The purpose is to provide sufficient nutrients and moisture during the germination of the seeds. Compared with applying it directly to the field, it saves a lot of cost; moreover, sowing the seeds in one place is convenient for unified management, and when transplanting, choose strong seedlings for transplanting.

Cultivate seedlings

1. Choose a variety

When choosing cauliflower seeds, you should choose varieties with full grains, drought-tolerant and disease-resistant varieties to purchase and retain seeds. Planting in different seasons under natural planting has different requirements for temperature resistance of cauliflower varieties, which are divided into summer and spring and winter sowing. The former chooses high temperature resistant varieties and the latter chooses low temperature resistant varieties. But for greenhouse planting, growers can intervene in the growth environment of cauliflower to a strong degree. The influence of seasons and climate characteristics on cauliflower is reduced to a very low level. It can be planted throughout the year. The requirements for this aspect are relatively low. Not too sensitive.

2. Cultivate seedlings

Choosing good seeds requires cultivating seedlings. One day before planting, the selected seeds can be placed in warm water for a period of time to allow the seeds to absorb sufficient water, end the dormancy period early, activate the seeds, and promote better germination of the seeds.

Then sown the soaked seeds in the nutrient soil block. Pay attention to the seeds to be evenly sown to avoid the seeds gathering in one place. The roots of the seedlings are not easy to separate the seedlings when the seedlings are planted.

3. Planting seedlings

Planting refers to the process of transferring the cultivated seedlings to the soil. At this time, the ability of the seedlings to adapt to the environment and the ability to resist external hazards is relatively low. In order to improve the survival rate of the seedlings, the grower needs to pay attention to the seedlings. care. Before transplanting, rectify the land to provide a more suitable environment for the growth of cauliflower seedlings. When pulling out the seedlings, you must bring a part of the soil, which can prolong the storage period of the seedlings and help the seedlings adapt to the new environment more quickly.

Soil preparation

1. Plow the soil

Soil agglomeration and drying under natural conditions are not suitable for the growth of cauliflower. Plow the soil to remove large agglomerations in the soil and improve the looseness of the soil; reset the nutrients in the soil to make the nutrients evenly distributed in the soil Among them, the growth of cauliflower seedlings is more consistent after planting, which is convenient for future care; exchange the deep soil with the surface soil to renew the soil, which is more conducive to the long-term development of the soil. Furthermore, plowing the soil can plow out the nutrients and pests in the soil. The nutrients are supplied to the cauliflower seedlings for absorption and use. The harmful bacteria and insects are removed through direct sunlight and drugs to reduce the pests in the soil and reduce the effects of pests on the cauliflower plants. The adverse effects.

2. Apply base fertilizer

If you choose to use drugs to repel pests, then fertilization should be delayed to prevent the harm of drugs from being eliminated, which will reduce the efficacy of fertilizers or the drugs and fertilizers will react to produce harmful substances or emit a lot of heat under certain circumstances, destroying the structure of the soil, and affect The growth of cauliflower seedlings. The base fertilizer can be organic fertilizer or farmyard manure to supplement the organic nutrients in the soil, and then based on the accurate measurement of the soil npk sensor to supplement the scarce elements, such as potassium, phosphorus, sulfur, calcium, etc.

If farmyard manure is applied, the decomposed farmyard manure must be used. The ripening of farmyard manure must meet strict standards. It must be processed in a regular factory. Under natural conditions, the air-dried farmyard manure does not reach the standard for decomposing. When applied to the soil, it will produce a large amount of decomposing. The heat burns the seedlings of cauliflower.

3. Reasonable irrigation

There is less water in the soil, and cauliflower needs to absorb a lot of water during the seedling stage. The water in the soil cannot satisfy the absorption of seedlings. Irrigation must be carried out reasonably. The soil moisture can be supplemented by spraying, and the sprayed water can be better. Infiltrate into the soil to improve the water storage capacity of the soil, better preserve water, and supply cauliflower seedlings for use. Using a soil moisture sensor can accurately measure the soil moisture content, so that the soil can be properly irrigated.

Field management

1. Remove weeds

There are usually some weed seeds in the soil. The vitality of weeds is more tenacious, and the ability to adapt and resist is also strong. It is a major hazard to the growth of cauliflower. Growers should regularly remove weeds in the field to prevent weeds from competing for soil. The nutrients and water contained in it provide a more suitable environment for the growth of cauliflower.

2. Control of pests and diseases

From a biological point of view, there are three methods to prevent pests and diseases: one is drug control, the other is physical killing, and the third is biological control. The two most common methods are drug treatment and release of natural enemies of pests that are easy to erode cauliflower. , According to the specific pests and diseases, choose appropriate methods to repel pests. However, the concentration of drugs and the number of natural enemies must be strictly controlled when controlling diseases and insects, so as to avoid excessive drugs or excessive numbers of natural enemies from harming the growth of cauliflower.

The above are the negligible and error-prone planting and management methods summarized from the aspects of seedling cultivation, soil preparation and field management. The use of scientific planting methods and skills, combined with the care and effort of the grower, can effectively increase the yield of cauliflower , Improve the income of growers.
