Cucumber growth is not good, yellow root is the cause?
Consultation: Jingyuan growers inquired that the cucumber planted in the greenhouse had been for more than 20 days. The growth was not good and the root was yellow. I wonder what the reason was. How to solve it? Answer: The cause of this phenomenon may be: 1. The old-age seedlings are planted, and the seedlings are slowed after being set. 2. When the planting was not done well or after the planting, the water could not be irrigated timely. Therefore, the roots did not contact well with the soil, causing hanging seedlings. 3. Before the planting, insufficient organic fertilizer was applied. About 15 days after planting, the organic fertilizer began to decompose and produce a large amount of harmful gases, which caused the root system to suffer damage, yellow breathing, and no new roots. Can be solved as follows: 1. If it is the slow seedling growth caused by the old seedling planting, it is necessary to strengthen the management of fertilizer and water, maintain sufficient water, and cooperate with foliar application of plant power 2003, Yuntaisu and other plant growth regulators. 2. Conduct field inspections and fill the soil with soilless seedlings. 3. Shallow ploughing in time, loosening the soil, irrigating the water, draining the harmful gas from the soil, speeding up the decomposition of the fertilizer, and promoting the development of the root system
