Care points for melon root care
1. The roots of watermelon are deep-rooted, with a primary root depth of more than 1 meter and lateral roots extending up to 4-6 meters. The main root groups are distributed within 10-40 centimeters of the soil layer. The regenerative ability of the root is weak, and it is not easy to recover after injury. Live production is often used. If seedlings are transplanted, the roots must be maintained.
2. Be careful not to focus on fertilization during planting. Unripe farmyard fertilizers will be fermented after being applied to the soil, which will produce high temperatures and a lot of harmful gases. Usually, it will cause the roots of the watermelon to die, so it must be noted. Do not concentrate on fertilization.
3, be careful not to plant too deep. Now the friends of Guaon are all using grafted seedlings for production. The grafting of watermelons uses varieties that are prosperous and resistant and have strong resistance, and they are grafted and cultivated. Satisfy the water and fertilizer demand of watermelon, and effectively improve the disease resistance of watermelon. If the planting is too deep, the watermelon will give birth to the regenerative root, then the grafting effect will be lost and the purpose of grafting will not be achieved;
4, be careful not to spray at noon or evening. Noon spraying temperature is too high, leaf water transpiration fast, the drug has not absorbed, it dried; late spraying just the opposite of noon, because the spray is not completely absorbed by the watermelon leaves, it will break down due to moisture, Failing to achieve the goal of treatment, it will aggravate the disease.
5, be careful not to fall too low. A one-time fall is too low, will lead to reduced light receiving area of ​​the leaves, affecting the photosynthetic efficiency, and then affect the normal growth of melons.
