How to cultivate bok choy? A detailed explanation of the latest planting techniques
Bok choy is called different names in different places; some call it green vegetable, and some call it piao'er cai. It is a type of Chinese cabbage and is widely cultivated; except in winter, it can be planted in the open field in other seasons. It tastes fairly good and is a vegetable people eat in daily life. Because the planting period is long, the planting time is short, it matures quickly, and it is convenient to prepare, it is loved by people. The process of cultivating bok choy is not complicated, but if you want to grow it well, there are certain points to pay attention to. Now let us learn about them together.
1. Planting time
From August to November, piao'er bai can be sown, and it can be sown in spring. When spring temperatures rise somewhat, it can be sown; spring has a lot of overcast rain and is prone to damping-off disease. Direct sowing in summer grows faster, but there are many weeds and many insects, and it is prone to downy mildew. Sowing in autumn during the little Indian summer results in less disease and fewer pests and a short growth period. It can be planted in all of them. Winter temperatures are too low, making planting difficult, so protected cultivation can be used.
2. Land preparation
Choose a piece of soil higher than a paddy field for planting. The soil is best neutral to slightly alkaline, and it must have good fertilizer retention and air permeability. It requires convenient drainage, but it should not be too dry. The root system of Chinese cabbage is not deep, and it has a high water requirement. Make the land into raised beds for planting. The raised bed is about 1.2 m wide, and the length is determined by the terrain, but it is best not to exceed 5 m, as that is not good for drainage.
3. Sowing
For seedling raising, seeds can be broadcast directly on the bed surface, and after emergence, thin the seedlings and weed. If watering is relatively heavy, loosen the soil a little. For seedling raising, transplant when the plants grow to 8 cm tall. The transplanting plant spacing is 8 cm, and the row spacing is 10 cm. In field planting, it is fine if it looks suitable. When transplanting, lift the seedlings gently to damage the roots as little as possible, and water once with dilute fertilizer water in the first three days. For direct sowing, dig small holes in rows on the bed surface and sow, with about 5 seeds per hole, plant spacing of 10 cm, and row spacing of about 15 cm. After sowing, cover with peanut shells to keep warm and moist, and water frequently.
4. Management
Bok choy has a shallow root system and little distribution, so it does not absorb water easily, but it needs a lot of water, so water little and often. Also, because the root system is weak, it is very afraid of root damage, so there must be no waterlogging, and it cannot be flooded all at once. Fertilization cannot be done all at once with too much chemical fertilizer applied dry; fertilization should mainly use farmyard manure. Use a small amount of chemical fertilizer; when applying chemical fertilizer, there is no need to cover with soil, and finally apply it together with water. Because the growth period is short, topdressing is roughly once half a month after the seedlings are established, with 30 jin of urea per mu at a time.
Cultivation includes the specific methods of planting and also the detailed management during the growth period. In any case, as long as the operation process is for the good growth of bok choy, it is all part of cultivation. Therefore, cultivation is a comprehensive kind of planting management.
