Rape with a good four "dowry"
1. In the middle stage of rapeseed cultivation, it is generally used to control the feeding of fertilizers in the middle of rapeseed nursery. In order to increase the carbon content, the seedlings will be controlled with little or no nitrogen fertilizer, which will help the seedlings to make a smooth transition from the leaf stage to the full period of strong seedlings. The goal. However, the rooting ability of rape seedlings is closely related to the nitrogen level in the body. If the nitrogen content in the seedlings is low, the rooting power is weak. Therefore, rapeseeds must be topdressed once before raising seedlings to increase nitrogen content in rape seedlings and enhance rooting power. In addition, due to the short interval between transplanting and transplanting, the oil seedlings can be relied on the accumulation of their own nutrients to maintain vitality, grow new roots, and quickly recover their growth. Adaptable. Practice has proved that the use of rapeseed to send the manure, live trees after returning green fast, leaves withered off less. Sending marrying manure is generally suitable for 7 days of 5 days in advance of transplanting, and about 75 kg of urea can be topdressed per acre seedbed. The application method is generally applied by spraying or dissolved in water, diluted and poured, depending on the humidity in the field. 2. Play a drug on the seedbed before transplanting the grafted rapeseed. On the one hand, it can eliminate the bacteria and pests attached to the seedlings, protect the seedlings from pests and diseases, and prevent the spread to the field. On the other hand, transplanting with drugs can also suppress the pests and diseases that remain in Daejeon. Therefore, it is a measure for the prevention and control of pests and diseases that saves labor, saves money, and is more economical. It is advisable to spray the herbicide 1 to 2 days before transplanting. The medicine can be selected according to the occurrence of local rape seedlings. 3. Spraying once to protect the boron rape is a boron-loving crop, which lacks boron at seedling stage, and the growth is atrophic. The heart does not grow. After transplanting rapeseed, if the soil is deficient in boron, or if it encounters drought, rain or other abnormal weather after planting, it will affect the growth of roots and weak absorption capacity, which will cause the lack of boron-free seedlings. Therefore, spraying boron fertilizer solution once before transplanting can prevent boron deficiency after rape planting. Boron fertilizer is usually sprayed for 2 days to 3 days before transplanting. The borax 150 grams per acre seedbed is used. It is fully dissolved with a small amount of warm water, and then diluted with water to 75 kg evenly. 4. Pouring up once the water rape often encounters dry weather during the transplanting stage, and it should be poured once before raising. One is that the soil is moist after watering, and it is easy to raise seedlings; the second is to reduce the injury and bring more mulching roots, so that the seedlings can be planted in the field quickly and grow new roots, early living trees, and soon return to green; third, the water content in the seedlings High and drought-resistance capacity is enhanced. After planting in the field, it is not easy to lose water and dry, and the phenomenon of dead seedlings occurs. The roots are strong, and the growth is quick. Get up and water should be poured in the evening before raising seedlings. It is easy to raise the soil until the soil is wet and it is easy to raise the seedlings. It is necessary to start the seedlings in the morning of the second day and transplant them in the afternoon. Watering time should not be too early, otherwise it will grow too tender due to adequate moisture, stems and leaves crisp, easy to damage the leaves and break off seedlings.
