I. Planting prospect
Okra can improve people's digestive ability, prevent various cardiovascular diseases and improve people's resistance. In addition, okra can be used in leisure agriculture and combined to form an integrated form of planting, picking and selling. Its planting prospect is very considerable. You can also sell fresh fruit okra and export it, and its economic benefits are very good.
Second, the cultivation techniques
1, planting time
The planting time of okra also has a great influence on the yield of okra. If it is planted too late or too early, the yield of okra will be reduced. It is best to sow okra in spring, but the temperature difference between north and south of China is quite large. It is best to plant it in March in the south, May in the north and April in the coastal areas. Appropriate planting time, the emergence rate and survival rate of okra are higher, and the growth is better, and the yield in the later stage is higher.
2. Variety selection
Okra is not a native vegetable in China, so there are not many varieties of okra in China at present, so it is relatively simple to choose varieties. In order to improve the yield of okra, we should first consider the varieties of okra that are suitable for local cultivation in China, and then see which varieties have high yield and high quality, and then choose the varieties with the best economic value in the current market for planting.
3. Adjust the density
We need to adjust the planting density if we want to produce high yield after planting okra. The first is to ensure the full use of land resources, and the second is to ensure proper ventilation and light transmission.
Then we'd better keep the row spacing of okra planting at 40-50 cm, and the plant spacing at 35-40 cm, and plant it reasonably according to the fertility of the selected planting site.
4, reasonable thinning
The arrangement of branches and leaves and the adjustment of plants are also very effective for improving the yield of okra. When the okra grows to a height of 30 cm, we need to remove the heart leaves at the top of it to promote the growth of branches. If there are too few branches in okra, the yield will naturally not be very high, because it has few fruiting branches.
In the process of promoting the growth of branches, it is also necessary to properly adjust the plant shape, at the same time, it is also necessary to control the number of branches, and sort out the branches that grow too densely or grow weakly and grow too long. In fact, simply speaking, it is necessary to reasonably control the permeability between branches and improve the result rate.
5. Topdressing
Okra is a deep-rooted plant, which has a strong ability to absorb nutrients and needs a lot of nutrients. If the soil fertility is insufficient, it will cause short plants and malnutrition, which will seriously affect the yield of okra. Because the fertility of the soil is insufficient, after the nutrients are absorbed by the roots, it is mainly to promote the growth of the roots, and it is impossible to supply nutrients to the branches and leaves, let alone bloom. Therefore, when applying fertilizer, we must apply enough. If there is not enough amount, it is equal to applying in vain.
These are the planting prospects and high-yield cultivation techniques of okra. You can collect them for later use!
