Broccoli is a type of vegetable in the cross bouquets, which were very popular in the mediterranean. It's nutritious, high vitamin vegetables. It is already widespread in the country. Plantation is possible in both the north and the south, but what are the specific conditions for planting, providing adequate conditions for planting, and also for growing well. Then let's find out now。
Conditions for growing broccoli
Temperature
The vulnerability to freezing below zero levels makes it very difficult to cultivate the ground during winter. And it's hard to create a flower ball at more than 25 degrees, and it's very demanding for temperature. It's not cold or hot. It's 20 to 25 degrees. But when a flower ball is formed, it's going to have to go through a cold spring. Or the ball won't be good. It's about eight degrees。
Soil
For soil requirements, it is a fertile sandy soil, with some deep soils, as root systems are more capable of growing, grounded soils, and roots are poorly grown. The acid alkalinity is about 5. 5. Some of the soil accumulates a little bit of salt, but it is better not to grow in saline. Soils with a salt content of 0. 5 per cent are still growing and are very difficult to adapt。
3. Water
The water requirements are stringent and must be dry, wet, dry, wet, water-free, flood-free and water-squeezing. However, drought is not enough, drought is not enough, and the soil must be watered and not drier. We can't tie it together. The moisture is not easily permeable. There is a need to maintain a particle structure and a good tectonic seepage structure. Good to keep 65% moisture。
4. Light
The light requirements are not stringent, but neither does it require light or receive too long. It's just that the sun can grow in normally growing areas. In fact, there is a need for sufficient light to keep the balls tight, better color, green leaves and good light cooperation. But there's not enough light, the balls are small, the colors are dim。
The temperature and moisture required for the cultivation of broccoli are more stringent; however, soil and light requirements are not so strict that conditions can be readily available。
Plantation methods and field management
1. Land selection
Vegetables cannot be planted in barren fields, otherwise they will not grow well, and they will choose a fertile cropland, a sandy sandy soil that is well-fed and well drained, which must be nuanced, well ploughed, soaked, soaked, soaked, soaked, soaked, soaked, soaked, so that the soil is not sick。
2. Sowing attention
Vegetables are cold, semi-cool-resistant vegetables, which cannot be so hot as to sow, but not so low, that otherwise they cannot germinate, it is good to sow in the early spring and april, and be careful to sow when the seeds are small, so be careful not to drop too many seeds. Of course, it's too difficult to sow by cave, so it would be better if we could prepare a seedbed, grow a seedling and then plant it. The seeding is carried out in such a way that the soil surface is sprayed, the temperature is protected against evaporation, the sun is protected against drought, the soil sheeting, etc., and the seedbeds are isolated from the infestation sources in order to increase the seedling rate。
3. Retiring on schedule
In the spring, when the temperature is low, the seedlings grow slowly, usually 45-60 days, and can be grown after the four-to-five leaves are grown. When planting, care must be taken that the field is flattened and the seedlings are reasonably spaced so that it can be managed later。
4. Field management
After planting, care must be taken that water, fertilization, weeding, pest control, etc. Must be kept moist, properly fertilized, weededed and sprayed in order to keep the cabbage healthy. When the florist comes out, care is taken that the environment in which it grows cannot be affected by adverse factors such as high temperatures, drought, frost, otherwise the growth of the florist will be shortened, the flowers will not grow long or will spread quickly, resulting in small and loosely small bouquets, and it will be difficult to reap good harvests, not only for production, but also for quality. In addition, during the extended seasons, extra fertilizing is required to ensure that the gratuity chubs are grown and solid and that the harvest is strong。
