Key Points for Vegetable Farming Management During the Winter Solstice
[Agricultural Techniques Micro Classroom]Winter Solstice Solar Term Vegetable Farming
In the North, the Winter Solstice has the shortest daylight. For vegetables and melon-fruit crops grown under protected cultivation, you should uncover early and cover late to let in more sunlight, so as to raise the temperature and promote growth. You can use Zhongtian brand plant grow lights for supplemental lighting.
For topdressing overwintering vegetables, it is best to apply per mu 5 kg of Quanneng Potassium King + 1 kg of Xindongli, flushed with a small amount of water; this gives good root nourishment and fruit swelling. Alternatively, apply per mu 2 kg of Lujian + 2 kg of Peigen as a flush to nourish the roots, which gives good results in lifting the growing point.
Solanaceous fruit vegetables require a temperature of around 20°C, melon-fruit types should be kept at 20-25°C, and leafy vegetables are best kept at 15-20°C.
Increasing light: orient the greenhouse north-south, frequently wash the plastic film, and choose light-transmitting film.
For overwintering seedlings of eggplant, tomato, sweet pepper and the like, management should be strengthened with multi-layer covering to promote strong seedling growth. During the seedling stage, you should also thin the seedlings, pulling out weak seedlings, yellowed seedlings and overly thin, leggy seedlings, and prick out and transplant them. At the same time, avoid excessive humidity that causes disease, and in particular pay attention to preventing seedling damping-off.
Strengthen water and fertilizer management and cold-protection measures. Sow cold-hardy leafy greens such as baby bok choy and spinach to supply the early spring market.
For warm-loving crops such as cucumber, sweet pepper and tomato in winter warm sheds, prevent downy mildew, gray mold and leaf mold. For resistant gray mold: fruit types
1. First remove the diseased flowers and diseased fruits;
2. First spray with 30 g of Jingtuling mixed with 10 gong of water using a mist sprayer;
3. Then spray with 25 g of Kaize + 20 g of Baijunke + 50 g of brown sugar + 30 g of Zhuangyuanjia mixed with 30 jin of water; the effect is good, improving control results and promoting growth.
