So, do you know the methods and steps of growing broccoli? Learn these five points, and you can easily plant them!
1. What are the planting methods and steps of broccoli?
1, planting time.
Many people think that broccoli is a crop that is available all year round, but it is not.
Generally speaking, broccoli can be planted for two seasons.
The first season is planted in March and the second season is in July.
The first season begins in mid-March and can be harvested in June.
The second season will be sown in July and harvested in September.
2. Selection of varieties.
When planting broccoli, the choice of varieties is also very important.
The high yield of broccoli depends on the selection of high-quality varieties.
The yield of broccoli is determined by the high-yield performance of its varieties and the quality of seedlings. When choosing broccoli seedlings, we must choose varieties with high yield, health and strong disease resistance.
But also depends on the actual situation, according to the local climate, local market preferences and environment to choose high-quality broccoli varieties suitable for local cultivation and strong heat resistance.
3. Choice of land.
When planting broccoli, the requirements for soil are not very high.
The sandy soil is breathable, which can improve the yield of that orchid to a certain extent.
Before planting broccoli, the soil should be composted and weeds should be eradicated. It should be noted that when planting broccoli, the higher the terrain, the better the drainage.
The optimum PH range of planting soil is 6-8, and the optimum PH value is 6.
Because broccoli needs sufficient fertilizer in the whole development and growth process, soil fertility is the most critical.
The demand for nitrogen in broccoli seedling stage is relatively high, and the demand for P and K increases after flower germination and differentiation. Therefore, proper application of foliar fertilizer before germination is more beneficial to the overall growth of broccoli, and at the same time, it will also improve the quality and yield of broccoli.
4. Culture conditions.
The cultivation of broccoli does not require strict light, but in the process of broccoli growth, adequate light is more conducive to the healthy growth of plants, which can promote their absorption of nutrients and make them better photosynthesis.
However, the exposure to sunlight is not conducive to the growth of broccoli, and the direct sunlight time should be controlled at about 6 hours. If it exceeds this time, it will easily cause a large area of sunburn to broccoli.
In terms of temperature, broccoli itself has strong heat resistance and cold resistance, and the optimum temperature is generally controlled within the range of 5-20℃.
Generally speaking, the higher the temperature, the faster the growth and development of broccoli. When the temperature is higher than 25℃, it is easy to affect the quality of the flower ball.
But as long as it is not frozen, the flower ball can grow slowly at 5℃ or lower, and it has strong vitality.
In terms of moisture, broccoli needs a lot of watering during the whole growth process, especially when it grows vigorously.
Broccoli cannot grow without water. If it is dry, it will seriously affect its output.
However, too much rain or too high soil humidity at seedling stage is not conducive to its growth and development, and it is easy to cause other diseases such as black rot and black spot.
The soil moisture should be kept at about 80% during the flower ball formation period to ensure its normal growth.
5. Prevention and control of pests and diseases.
Broccoli is planted in spring, and there are relatively few pests and diseases.
Common diseases and insect pests include aphids, Pieris rapae, whitefly, black spot, black rot and so on.
You can prevent pests and diseases before planting broccoli. Seeds are usually disinfected with fungicides before planting.
When transplanting broccoli, the land can be ploughed 10 days or so, and the land can be sterilized by sunlight to kill the germs hidden in the soil.
If there are pests and diseases on broccoli, low-concentration pesticides can be sprayed to prevent a large number of pesticides from remaining on broccoli.
To sum up, the prevention of broccoli is greater than the treatment. If we work hard at the first step of prevention, we can minimize the losses caused by pests and diseases.
After reading the above broccoli planting methods and steps, I believe you can easily plant it in front of the screen!
