1. When the leek is rooted, the harvest is stopped. After the cutting, the leek grows and falls easily. After the field is concealed, the disease is often rotted. Therefore, it is necessary to pull the wire on both sides of the leek to prevent the leek from falling down. The field is ventilated and light, maintaining the photosynthesis of leek, promoting the growth of leek and reducing the occurrence of pests and diseases.
2. The temperature in autumn is getting lower, which is good for the growth of amaranth. Before the rapid growth of leeks, a heavy topdressing should be carried out, and a new high-fat film should be sprayed to increase the fertilizer efficiency and spread the disease-preventing bacteria. When topdressing, use bamboo rafts to move the leeks to the sides from each line to expose the inter-row ground and open the small ditch. Spread the bean cake inside, then cover the soil. After fertilization, pour a large amount of water. You can also water the water first. After the dough is suitable, use the bamboo poles to divide the leeks from the rows to the sides. Spread the bean cake between the rows, then sculpt, mix the bean cake with the soil and then work hard. Watering once every 5-7 days.
3. The main diseases of amaranth are disease and gray mold. High temperature and humidity are the main causes of the disease. According to the introduction of Chinese farmers' planting network, targeted drugs must be used. In order to improve the control effect, it must be used together with the new high-fat film. The pesticide is poisoned, the poisoned pesticide is low toxicity, and the low toxicity pesticide is slightly toxic. Control the volatile and volatile pesticides, prevent the rainwater from scouring, reduce the dosage per acre (half), and improve the control effect (multiple times). The roots are treated with roots and roots together to water the roots.
