Eggplant is a kind of warm-light and long-day plant. It is one of the common vegetable crops in China. It is easy to obtain high yield in early spring planting, and the economic benefits in the market are also high. Before and after the Qingming Valley rain, it is just the farmer who grows eggplant seedlings. Busy time. However, in the process of planting eggplant in spring, it is necessary to grasp the law of seeding time in order to avoid affecting the yield of eggplant. At the same time, when the eggplant seedling grows 3 pieces of young leaves, it is necessary to carry out timely transplanting treatment. So what is the specific content of this series of processing? Let's take a look at the footsteps of Hui Nongwang Xiaobian.
Planting time of eggplant seedlings
Eggplant can be cultivated in both north and south of China, and different regions are limited by geographical location and climatic conditions, and their planting time is also different. For example, in areas with low temperatures in the north, eggplants in early spring can be planted in March and April, and can be planted in about 50 days. In the south, it only takes about 30 days, and it is recommended to plant seedlings in the middle and late March.
The spring greenhouse cultivars can be planted at the earliest from November to December, and the seedling age is controlled at 70-120 days. Of course, regardless of the variety, it is necessary to make appropriate time adjustments according to the actual temperature conditions.
Main points of cultivation management of eggplant seedlings
Before carrying out seedling sowing in early spring, it is necessary to strictly screen the varieties of eggplant seedlings. It is recommended to choose varieties that are early maturing, cold resistant, resistant to pests and diseases, and resistant to low light. In the process of cultivation, it is also necessary to provide suitable growth temperature (25~35 °C), which is beneficial to the germination of eggplant seedlings. Its management points can be summarized as the following four points:
1. Colonization management. Eggplant planting should not be heavy, so try to choose the plot that has not been planted with Solanaceae crops before planting. For the convenience of irrigation and drainage, the plot needs to have loose and breathable soil and flat terrain. At the same time, it is necessary to apply sufficient base fertilizer before the fixed value, generally with fully decomposed farmyard manure and with potassium sulfate fertilizer.
2. Water and fertilizer management. After planting, the seedlings are poured once a week, and then drip irrigation or small water flooding can be carried out according to the soil moisture. In the late stage of watering, the top dressing is carried out according to the growth of eggplant. Generally, the first top dressing is carried out when the eggplant starts to expand. The urea is applied for about 15 kg per mu or 20 kg of ammonium sulfate, and is applied once every 15 to 20 days.
3, pruning. The pruning process is one of the most important tasks for most vegetable plants. During the vigorous growth period, the dense foliage will occupy the growth space of the eggplant and affect the ventilation of the whole planting area. Therefore, the side branches under the first branch should be removed in time. The old leaves and the deformed fruits under the eggplant are removed, which increases the ventilation and light transmission capacity of the whole plant.
4. Pest control. The main insect pests of eggplant are red spiders and aphids. The main diseases include squatting and verticillium wilt. According to the law of pests and diseases, timely prevention and control can effectively reduce the impact of pests and diseases.
The above is about the planting time and cultivation management points of eggplant seedlings. Only by mastering the skills, can increase the eggplant yield.
