Qiuyan Vegetable Seedling Technology
1. Selection of cultivars: During the early autumn period, the differences in the temperature and moisture of the vegetable nursery are large, and the basic conditions for the low-temperature and low-temperature illumination in the later period make the selection of varieties suitable for the wide-suitable, disease-resistant, cold-resistant, and high-yield species.
2. Pay attention to the dangers caused by high temperature and heavy rain at the seedling stage: High temperatures and heavy rain will inhibit the growth of vegetable seedlings and cause diseases and insect pests. Therefore, shade nets and insect nets are used during nursery to effectively prevent high temperatures, heavy rain, and insect pests from occurring.
3. Prevention of pests and diseases: During the autumn period of vegetable seedling raising, pest control nets can be used to effectively prevent pests; contiguous vegetables can be trapped and killed by frequency-vibration insecticidal lamps to reduce the density of cuts; and the use of highly effective and low-toxic pollution-free pesticides is advocated.
4. Appropriate fertilizer management: During late autumn vegetable nursery, strict management of seedbed fertilizers and water should be implemented to ensure that seedling fertilizers and water are prevented from growing too much while causing excessive growth.
