How to protect cucumbers during winter planting?

The first point: Pay attention to disinfection of the greenhouse soil to reduce the number of residual bacteria. The soil is a hotbed for many diseases to overwinter, spread and multiply. Common diseases of cucumbers such as anthracnose, gray mold, sclerotinia, and fusarium wilt are spread through the overwintering of diseased branches and leaves in the soil. Therefore, when raising seedlings and transplanting Soil must be disinfected before planting, which can effectively reduce seedling disease susceptibility and prevent premature aging of cotyledons. Before soil preparation, we can use 150 grams of Jinnahai per mu, spray the soil evenly, and then plow the soil 10-20 centimeters. For example, in greenhouses where root-knot nematodes are seriously infested, Amote can be added when spraying Jinnahai. The dosage of Amote for controlling root-knot nematodes per mu is 1000 ml.

The second point: seedbed management. There is a need to pay attention to the soil in the seedbed. You can use corn field or wheat field soil to raise seedlings. The seedbed soil should be flat. Use Jinnahai to disinfect the soil 2 days before sowing. Using nutrient soil blocks is a better choice. When watering the seedbed, it is also necessary to add Stockop and Jinnahai. Use 2.5 grams of Stockop and 10 grams of Jinnahai per 10 square meters of seedbed to increase the seedling emergence rate and reduce seedling damping-off, blight and blight. Occurrence of cotyledon anthracnose. Fertilizer should be applied evenly on the seedbed to avoid excessive concentration that will damage the roots and burn the seedlings. If farmyard manure is used, it needs to be applied after it is decomposed. Applying Stockop on the seedbed will not only improve the absorption of fertilizer by the melon seedlings, but more importantly, promote the growth of the root system. Cultivate high-quality seedlings. Point 3: Things to note when grafting cucumbers. Since grafting will inevitably cause wounds to the melon seedlings, it is necessary to pay attention to the invasion of diseases from the grafting interface. 1-2 days before grafting, spray the seedlings with 1500 times of Rousuiton + 1000 times of Nanoxin + 6000 times of Stekop to enhance the disease resistance of the seedlings, promote the healing of the grafting interface, and prevent the invasion of diseases from the grafting interface! The seedlings treated with Roushuitong + Nanoxin + Stekop slowed down quickly, healed the grafting interface well, and developed the root system well. Point 4: Things to note when planting: The root system of cucumbers will be damaged during planting. The development of the root system after planting plays a very important role in the resistance, disease resistance and premature aging resistance of cucumbers in the later period. Therefore, the protection and protection of the root system after planting It is important to promote rooting recovery. Planting is a critical period for the prevention and control of Fusarium wilt and bacterial wilt. Jinnahai must be added to the planting water for sterilization and disinfection to prevent the injured roots from being infected by diseases. The dosage of Jinnahai per mu is 150g, which can effectively control cucumber fusarium wilt and bacterial wilt. The occurrence of root diseases such as root rot. After planting, spraying 1500 times of Roushuitong + 1000 times of Nanoxin + 6000 times of Stekop on the leaves can effectively promote root wound healing, accelerate seedling slowing, and promote rapid root growth. After planting, pay attention to "water control and seedling cultivation", strengthen cultivating, and increase ground temperature. After that, strengthen the observation of the melon seedlings. If the growing points appear wilted at noon and fail to recover in time in the evening, water will be needed to slow down the seedlings. If there is no wilting at the growing point in the evening, there is no need to pour water to slow down the seedlings. You only need to spray 1500 times of Roushuitong + 6000 times of Stockop + 1000 times of Nanoxin on the leaves to prevent diseases and promote growth.
