The "three avoidance" techniques for crops sheltering from the rain, avoiding the cold and avoiding the sun means adopting certain artificially simple and practical facilities, supporting appropriate technical means, adjusting measures to local conditions, seeking advantages and avoiding harm, and overcoming adverse environmental conditions encountered during the growth of cash crops. Fully, rationally and scientifically use temperature, light, and water conditions to achieve the purpose of pest control, pollution prevention, and disaster prevention. Avoiding rain, mainly anti-rainstorms, acid rain, and Meiyu; avoiding the cold, mainly anti-cold, frost; avoiding the sun, mainly anti-sunburn, anti-high temperature. The main modes of "three avoidance" technologies are the following types:
1. Fruit (for example, grapes): Covering the cold with plastic film cover (spring seedlings) + surface cultivation film cover + shelter from rain and half moon-shaped arch cover with plastic film cover + fruit bagging.
2. Vegetables (tomatoes, for example): Covering the greenhouse with plastic film (covering seedlings) + Avoiding sun exposure (seedings) Shading net cover + Daejeon surface cultivation film cover + shelter from the rain.
3. West melons (for example: Reticulated melons): Covered with plastic sheds for greenhouses (nursery) + Sun exposure (seedlings) Sunshade net cover + Daejeon surface cultivation film cover + Shelter for large and medium-sized greenhouses Shelter cover + Sun shade net cover.
4. Silkworm (in order to raise cockroaches as an example): Mulberry Park built a simple greenhouse to avoid rain, avoid the cold (agricultural film cover) + avoid sun exposure (shade net coverage).
5. Edible fungus (take shiitake mushroom as an example): evade the cold and shelter from the rain.
6. Tea (with white tea as an example): Covering the greenhouse with plastic film (coverage) + Covering with sun-shading nets + Covering with plastic film in Daejeon.
7. Chinese herbal medicine (taking silver lotus as an example): Covering the greenhouse with plastic film (covering seedlings) + Covering with sun-shading nets and covering the field with plastic film covering Daejeon.
8. Flowers (taking carnations as an example): sheltering from the cold and sheltering large and medium-sized sheds from agricultural film cover and avoiding sun exposure.
9. Tobacco (Spring flue-cured tobacco as an example): Large and medium arch shelters to avoid the cold, shelter from the rain (floating method seedlings) plastic film cover + avoid exposure (seedling period) shade net cover + surface cultivation film cover.
10. Cereals and oil crops (to prevent cold seedlings, plastic film corn and winter potato straw covered with no-tillage cultivation): shelter evade cold (or tiling) agricultural film cover (raising), plastic film cover (corn), straw covered no-tillage (potato) .
In addition to the above-mentioned various materials, other regions can use other materials according to the local actual conditions, such as: straw, crop straw, etc., combined with local practical cultivation techniques, single use or comprehensive utilization development for local promotion of "three avoidance" Technical cultivation mode can be.
