Problems solved by technology
In the southern region, the sparse planting method and the root zone restriction method are often used to plant in multi-span film greenhouses. This will easily cause the temperature in the shed to rise rapidly in the initial stage of growth because there are fewer crops in the facility and the leaf area is also small. Humidity changes greatly, affecting the normal growth of plants

Embodiment Construction
[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0016] The invention discloses a method for maintaining moisture and reducing temperature in a multi-span film greenhouse. Alfalfa grass is planted on the idle ground in the multi-span film greenhouse where main crops are planted.
[0017] The planting method of the alfalfa is drill sowing with a row spacing of 20 cm, and the sowing depth is 6-10 cm.
[0018] The planting density of described alfalfa is 400 plants / m 2 .
[0019] The planting time of the alfalfa is mid to late May and / or July-August.
[0020] Whenever the alfalfa grows to 50-55 cm, it is mowed to...

The invention discloses a method for preserving soil moisture and cooling in a continuous membrane greenhouse. In the method, alfalfa is planted on the idle ground in the continuous membrane greenhouse, in which a main crop is planted, and to be specific, the alfalfa is planted in line with spacing of 20 cm, the seeding depth is 6-10 cm, the planting density is 400 plants / m<2>, and the planting time is mid-to-late May and / or July-August. When growing to 50 to 55 cm, the alfalfa is cut to 8 to 13 cm, and the cut alfalfa is piled up and wetted to manufacture compost. Through row planting of alfalfa, the effects of preserving soil moisture and cooling can be achieved, weeds can be controlled, the cut alfalfa can be used for composting to obtain green manure, and the temperature in the greenhouse can be reduced, thereby promoting the growth of the main crop , achieving good economic benefits and saving more labor.
Description
technical field [0001] The invention relates to the technical field of facility cultivation, in particular to a method for maintaining moisture and cooling in multi-span film greenhouses. Background technique [0002] At present, multi-span film greenhouses have been widely used in facility cultivation, but the temperature in the facility is relatively high, especially during the high temperature period in summer. In the southern region, the sparse planting method and the root zone restriction method are often used to support multi-span film greenhouse planting. This is easy to cause the initial growth period because there are fewer crops in the facility and the leaf area is also small, resulting in a rapid rise in temperature in the shed, soil surface temperature and Humidity changes greatly, affecting the normal growth of plants. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [00...
