Early spring membrane cover can significantly increase the temperature, improve protection capacity, maintain soil ablaze, contribute to root system growth, and promote early growth and growth. Covering the membranes can reduce the risks of disease, viral diseases, etc., and also reduce scavenging and significantly improve the production and quality of winter melons. The membrane cover is 15 to 40 per cent more productive than the uncovered。
1. Choice of varieties
Membrane-covered cultivation is generally for the purpose of early ripening, so it is advisable to choose pre- or medium-preparated varieties。

The membrane cover requires a high level of land quality and must be flat, earthy, base-based, suitable and high. First, the soil is removed from the precipice straw and from the ground with bricks and sheeting, and 5,000 kg of fattening per acre per farmer and 15 kg of calcium per phosphate, so that the soil is fully mixed with soil and the soil is dredged to the ground, and then the ground is levelled, drained and drained, water is poured into the water once, the soil is maintained with enough accelerations, and the topsoil is made as soon as it does not stick. The membrane cover is generally based on a high-swirl (swirl) approach. There is a difference between different types of pre-literate species, which are 10-15 cm tall, 60 cm wide, 40 cm wide, with a transparent membrane covering 90 cm wide, and medium-literate species, which are 10-15 cm high, 40-45 cm wide, 155-160 cm wide, with a transparent membrane covering 80 cm wide。
3. Cover the membrane
The whole site is followed by a membrane work. A proper amount of herbicide is sprayed before the sheeting, followed by a laceration, which requires that the sheeting be stretched to the surface of the soil, with no gaps left, and that the soil be levelled around and pressured to achieve optimal soil warming. The gutter is not covered and is kept for water and fatting。
4. Plantation
They can be planted either first after they are laid or later. The membranes laid first are of better quality and speed, but planting is difficult and difficult, and the latter method is easy to plant, fast and fast, and it is easy to ensure the quality of seedlings, but the membranes tend to damage winter seedlings and to flatten them. The thin membrane vents around the seedlings are subject to heavy earth pressure to prevent damage to the seedlings and the dissipation of the heat by the wind. A “smoke-side cover” is used to lay the film first and then to cover the chapter。
5. Fertilizer management
Because the membrane covers the face, it is not easy to water or fatten the roots of the winter, but only in the trenches, with horizontal infiltration to provide the water fat for the growth of the winter melon. In addition to foot bottom fertilisation, water can be used to pursue fertilizer or faeces and, if necessary, leaves can be sprayed。
