The quintessence of the management of Qiuzhuanzi

Scientific sowing.

The selected land will be ploughed and fertilized before sowing. Make a 1.5-meter-wide border, open a shallow ditch on the border surface, and mix the seeds with a new high-fat film before sowing, which can keep heat, moisturize, absorb swelling, improve the seed germination rate and make the seedlings strong. Repelling underground pests and isolating virus infection. Spread it evenly in the ditch and cover the fine soil after sowing so that the seeds are not seen.

Field management.

(1) replenishing seedlings. Seedling height 5 cm 6 cm time seedlings, according to the plant spacing of 15 cm 20 cm to leave 2 strong seedlings. If there is a lack of seedlings, uniform seedlings from around to replant. At the same time, weeding was carried out by ploughing and weeding, loosening the soil shallowly, with a depth of 5cm and 7cm. No longer ploughing after the row is closed, and the grass will be pulled up when you see it.

(2) topdressing fertilizer. Increase the application of nitrogen fertilizer in the seedling stage to improve the seedling, and increase the application of phosphorus and potassium fertilizer in the growing period. The fertilizer can be applied once in the interseedling and in the early stage of vigorous growth, and the photosynthetic nutrient film fertilizer can be sprayed on the leaf, which can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizer and nutrients to the limit of plant growth and development.

Pest control.

The main diseases and insect pests are root rot, leaf spot and aphids, which can be controlled by spraying targeted insecticides, which must be used together with new high lipid membrane to improve the utilization rate of effective components of pesticides and reduce the use of pesticides.
