Rice seedling non-woven fabric
But be careful not to pour the water on the seedbed before removing the mulch. Conventional dry seedlings use 167 grams of seedling-strengthening agent per square meter to be sprinkled on the prepared seedbed, mix with the surface soil evenly and then cultivate. Use mixed dosage form of high-efficiency herbicide Dingpu mixture to close the seedbed, and chemical weeding is based on the characteristics of the emergence of weeds in the drought-raising seedlings. At the same time, make sure that the height of each bed frame is the same after inserting, and then cover the non-woven fabric. The pot seedlings should be planted 350-400 grams per square meter, and 250 grams per square meter are conventionally used for dry seedlings. In the early stage of non-woven cloth seedling raising, try to maintain the temperature as much as possible, without ventilating the seedlings. Cover a layer of mulch film on the bed surface after cultivation, and cover it with mulch film in order to improve the pre-heat preservation and moisturizing effect of non-woven fabrics. There is no need to uncover the cloth, just pour water directly on the cloth, and the water will penetrate into the seedbed through the pores of the cloth.Problems and technologies in the non-woven fabric industry in agricultural applications
Rice seedling non-woven fabric
There are so many applications of non-woven fabrics in the agricultural field, what technical level has been reached now, and what specific application technologies are there, let us discuss together below. Cultivation Because the accumulated temperature in the early stage of non-woven seedling raising is low, the sowing date should be 2-3 days earlier than the proper use of agricultural film. But after entering mid-May, the outside temperature continued to rise. Spreading the rack strips Before inserting the rack strips, the area around 35 cm at both ends of the rack strips is processed into a curved shape, and the rack strips are inserted into a trapezoid shape. Sprinkle water in time Start watering when the surface of the bed soil becomes white and dry.
3.
4. It is necessary to extend the cover time of the mulching film to improve the effect of heat preservation and moisturizing in the early stage of seedling cultivation.5 leaves. The specific method is to use Nongken brand multifunctional seedling strengthening agent to make nutrient soil. Make the 3-layer design mask shed basically stick to a level surface, so that the water will not flow down from the cloth quickly when sprinkling water, which improves the effect of water leakage. Because the leaf age is relatively large, it will continue to be defertilized after 3. Conventional dry seedling cultivation.
1. Can meet the needs of the entire seedling period. Choosing land as a bed It is best to choose a yard or high platform for the seedling raising address.
2. After the seedlings are all out, remove the mulch when the first leaf on the list is completely opened. Several issues that should be paid attention to in seedling management
1. Manufacture of nutrient soil Because the non-woven seedling raising process eliminates the need for ventilating seedlings, top dressing is no longer needed throughout the seedling period.
6.5 leaves, the pot seedlings can be topped with the fertilizer once when the cloth is withdrawn before transplanting. When making the top dressing non-woven seedlings base fertilizer is sufficient, generally do not need to be fertilizer before 3. The pot seedlings per square meter (561 holes, 5 sheets) are mixed with 83 grams of strong seedling agent and 7.
Two, non-woven fabrics cover up the key points of seedling cultivation skills
1. When the temperature in the bed exceeds 30°C, the seedlings should be ventilated to avoid excessive growth of the seedlings and lowering the quality of the seedlings. To mix the rope, use nylon rope or tear film, do not use straw rope, so as not to wear the non-woven fabric and reduce the service life..
3. Level the bed surface, so that the bed soil is finely broken and there is no debris on the outside.
4. At this time, the appropriate amount of nitrogen fertilizer should be applied to promote the growth of grass seedlings.5 kg of black soil to become nutrient soil; therefore, it is necessary to create nutrient soil with sufficient nutrients and a reasonable share, and it will be fertilized once at the seedling field.
5. The ground for raising seedlings is less effective, so you should try to choose a place with a higher topography.
