There are many varieties of eggplant, and long eggplant is one of them. The biggest difference from ordinary eggplant is that it has a long shape. Long-planted eggplants need organic soil with sufficient light, fertile soil, and good water retention. Let's take a look at the key points of planting techniques for early spring long eggplants.
Illumination
Long eggplants grow vigorously, requiring suitable conditions such as long illumination time and high light intensity. Light promotes the formation of flower buds and improves the quality of differentiation, which is conducive to the normal development of fruit shape, full expansion of fruit, small waviness of fruit surface and bright color of peel, which is beneficial to improve the yield and quality of long eggplant. When the long eggplant is pruned, it is not necessary to remove the leaves covering the solanaceous fruit, so as to avoid direct sunlight on the solanaceous fruit, and the sunburn phenomenon and the yin and yang surface are caused, which results in a large discount on the commercial value of the long eggplant fruit.
2. Temperature
Long eggplant is a thermophilic crop. The suitable temperature for seed germination is 25~30°C. The suitable temperature for seedling growth is 25~30°C during the day and 15~20°C during the night. The plant grows slowly below 15°C, and the flowering period is easy to fall, 10°C. The following metabolic disorders, plant growth abnormalities; flowering results in the temperature range of 20 ~ 30 ° C is the best.
3. Moisture
The long water in the seedlings of the long eggplant is easy to cause the disease, and the water requirement is small before the flowering result; after the formation of the long eggplant, the long eggplant grows rapidly and the water demand increases, especially before the mature eggplant matures, and the normal dry humidity climate is also Manual hydration is performed as much as possible at intervals of 15 days. However, in the case of continuous rainy weather, it will cause soil moisture and compaction, resulting in poor oxygen transmission, easy rooting, and disease. Therefore, the long eggplant must be deep and high, and the rainfall is too large or the rainfall time is too long. Timely drainage.
Soil
Like most crops, long eggplants need to be grown in soils that are rich in organic matter, water and fertilizer. The long leaf volume of the long eggplant and the strong growth of the plant, especially in the early stage of the formation of the long eggplant, the demand for nitrogen fertilizer is large. Nitrogen deficiency can lead to delayed flower bud differentiation, and the number of spikes is significantly reduced. Insufficient nitrogen fertilizer during flowering period may lead to short flower style and insufficient development of long eggplant fruit. The growth of leaves in nitrogen-deficient plants is hindered and photosynthesis is reduced. . In the middle and late growth period of long eggplant, a large amount of solanaceous fruit was formed, and the absorption of potassium increased sharply. It is necessary to pay attention to potassium supplementation.
The above is the cultivation point of the long eggplant, the content is relatively simple, only for the reference of the farmers!

Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
