Such vegetables include tomatoes, eggplants and sweet peppers. The common feature of this type of vegetables is that there are many types of infinite growth, such as buds, flowers, and side effects. Therefore, in production, we must pay attention to adjusting the contradiction between vegetative growth and reproductive growth in order to obtain a better harvest. Only a sufficient supply of nitrogen can ensure normal photosynthesis and keep dry matter growing. Nitrogen deficiency in the early stage of fertility, the lower leaves are easy to aging and fall off, while the lack of nitrogen in the late growth stage leads to a decrease in the number of flowers and a lower rate of fruit set. However, excessive nitrogen is likely to cause excessive growth of vegetative bodies, easy to fall off after flowering, and limited fruit expansion. After entering the reproductive growth phase, the demand for phosphorus has increased dramatically, while the need for nitrogen has decreased slightly. Therefore, attention should be paid to the appropriate application of phosphate fertilizer to control the amount of nitrogen fertilizer. Adequate potassium can make photosynthesis of vegetables flourish and promote fruit enlargement. This kind of vegetables should pay attention to the fertilizer application of phosphorus and potassium fertilizer, and ensure the balanced supply of nitrogen, phosphorus and potassium nutrients. This is the guarantee of high yield and high quality of Solanaceae vegetables.
Espag handles are the most common type of window handle used today. A locking system with a flat metal strip which runs up the side that locks into the frame. The locking mechanism moves when the window handle is turned. They fix onto the window with two fixing screws and have a square spindle bar which protrudes from the base.
