Nursery site seven attention
In order to reduce blindness, the following seven issues should be noted when setting up a nursery site: First, the terrain should be good. Nursery should choose less complex topography, relatively flat open terrain, too large gradient can cause soil erosion, is not conducive to plant growth. At the same time, we cannot choose low-lying land to prevent long-term accumulation of water or flooding. Second, we must have excellent soil quality. The soil is the foundation for the growth of seedlings. It is necessary to select the loose soil as far as possible, the soil is deep, and the drainage, water conservation, and fertilizer retention performance are good, and the humus-rich land can ensure the growth and development of the seedlings. If we improve soil quality, we need to invest more manpower and material resources, and the relative increase in costs cannot be ignored. The third is to have a good water supply. When selecting the site, we must consider the source of the water according to the topography of the seedling field, and we can choose to have better self-flow irrigation. At the same time, we must also consider flood discharge during the rainy season. Fourth, the light should be good. You must choose sunny plots. Negative plants can use different shading nets and other shading measures to meet the needs of plants. If non-sunshine plots are selected, it is difficult for positive plants to meet the amount of light required, and the degree of restriction on development is too great, and the proportion of positive plants in seedlings is also significant. Larger. Therefore, we must choose the nursery for the sunny plot. Fifth, we must have a good environment. The space environment around the site must be fresh. In places where the water flow and air pollution are large, no matter how good the other conditions, the plants can hardly grow well. In particular, some seedlings have poor adaptability to fluorine, sulfur, and dust in the air, and poor growth; some may not even survive. Six will traffic. As far as possible, choose places with convenient transportation such as roads, railways and waterways to facilitate the transport of seedlings, increase the visibility of nurseries and speed up the circulation of seedlings. This is also an important factor in improving the efficiency and improving the nursery. Seven to power enough. Electronic temperature control, humidity control, light intensity adjustment, full-light spray cutting, and tissue culture are all inseparable from electricity. When water is used to draw water, the use of a pump requires electricity. Without electricity, the production is bound to be in the original state of operation.
