The greenhouse is ready before use.

Prepare vegetables before use in the greenhouse with high quality and high yield

At present, the vegetable farmers who cultivate overwintering out-of-season vegetables are going to start to make preparations before planting, so what work does the vegetable greenhouse need to do before using it?

Nutritious soil is made of fertile garden soil, rotten ring manure or compost retted in advance, and peat soil can also be used if possible. The above fertilizers are coupled with some fully mature farm manure and calcium superphosphate. The formula is as follows: 6 parts of loam soil without the same kind of vegetables, 4 parts of mature farm manure, 20,25 kg of mature farm manure, 1.5 kg of compound fertilizer, 0.08 kg of 50% carbendazim powder, 2 kg of superphosphate, sifted and piled up, covered with film, and can be used for a period of time.

If the seedling bed is prepared to raise seedlings with nutritious soil or sowing seedlings, the prepared nutritious soil can be spread directly on the seedbed. A few days before sowing, dig out about 10 cm of the original soil from the seedbed, flatten the bottom, and fill it with 12 cm thick nutritious soil. Melons and legumes generally do not divide seedlings in the process of raising seedlings, it is appropriate to use nutrition bowl to raise seedlings, nutrient soil can be loaded into nutrition bowl, and then the nutrition bowl can be closely arranged on the seedling bed dug down; the gap between bowls should be sealed with nutrient soil to prevent moisture loss after sowing. High-temperature stuffy shed disinfection, combined with chemical disinfection, can effectively kill a variety of bacteria. About 15 days before the use of the greenhouse, spray more than 10% of the dust agent on the ground in the greenhouse, 1 kg per mu; then turn the soil deeply to close the greenhouse; and apply 45% chlorothalonil smoke remover, spraying 1 kg per mu; after smoking, continue to close the greenhouse and use sunlight to form a high temperature inside the greenhouse; after 7-10 days of high temperature, 50% carbendazim wettable powder 800 times solution can be used to spray the skeleton, ground and walls of the greenhouse. The proper application of organic fertilizer by preparing fertilizer and fertilizing ridge is beneficial to the high yield and high quality of vegetable crops, but the organic fertilizer must be fully mature, otherwise it is easy to burn roots. In addition, the organic fertilizer to be applied into the greenhouse will be watered and humidified 50 to 60 days ahead of time, piled up, covered with plastic film, fully fermented, and then applied after ripening. In the low temperature season, it is best to do it in the greenhouse or other high temperature places. The rotten fertilizer can be spread in the greenhouse, and then turned deeply, leveled and ridged. (Chen Ligang)

How to choose and buy vegetable seedlings in autumn and winter

Autumn and winter and overwintering are the main stubble in many vegetable planting bases, which have the advantages of long growth time, high yield, high price and good benefit. In order to improve the seedling level of growers, here is to introduce the correct selection and use of vegetable seedlings to vegetable farmers.

? Characteristics of fine seedlings

The variety is suitable for local facilities (heat preservation capacity, lighting capacity, etc.), soil (soil type, soil fertility, pH value, salinity, etc.), climate (rain and snow weather, wind, temperature) and so on.

Good adversity conditions include extremely low temperature weather, long-term overcast and rain, light weather, soil salinization and other factors that are not suitable for vegetable growth.

Healthy and strong seedlings require strong stems, complete cotyledons, dark green leaves, strong growth; white and dense roots, dense root hairs, tightly wound the matrix to form a complete soil lump, no yellow leaves, no diseases and insect pests, and the whole plate of seedlings are neat and consistent.

The method of buying excellent seedlings

The seedlings should be fixed in advance. Many growers like to buy seedlings only when they like to plant, but they are often unable to buy strong seedlings of the right age.

Seedlings should be purchased from normal channels. At present, in order to reduce costs, some undesirable manufacturers use inferior seed scions, rootstocks and even fake and shoddy products, and some adjust seedlings in different places regardless of whether the varieties are adapted or not, and the seedlings are not quarantined.

It is necessary to sign the contract carefully and keep the documents so that there is evidence to check when something goes wrong.

Choose a seedling company with strong strength and good reputation. Good seedling company has excellent germplasm resources, advanced seedling facilities, equipment, mature seedling technology, good reputation, so it can ensure the quality of seedlings to the greatest extent.
