The seedlings, the seedlings, and the timely seedlings are germinated from seeds to fixed seedlings. Generally, the seedling age is about 18 days, and multiple seedlings should be carried out during the period. The seedlings were unearthed for 3 days for the first time, and the seedlings were separated. The 4th seedlings were 4-5 leaves, and 2-3 plants per hole . According to the strength of the seedlings, the strength is weakened. When the leaves grow to 8-9 leaves, the seedlings are fixed at a distance of about 50 cm. The time for the seedlings to be fixed should be mastered at noon at high temperatures. Due to the different ability to adapt to the environment, some weak seedlings and diseased seedlings show their morbidity, which is easier to identify and worse. If there is a shortage of seedlings, it should be replanted in time.
Â
The cultivating and weeding combined seedlings are carried out in the middle of the fixed seedlings and the rosettes respectively. According to the principle of “the head is shallow, the second is deep, and the third is not damagedâ€, the high ridge cultivation should follow the principle of “deep gully and shallow backâ€. The cultivating of alfalfa and the cultivation of soil, such as the late growth of the rosette, can be carried out.
Â
Watering and top dressing, such as the amount of base fertilizer, can be used to catch a fat at the seedling stage. Apply 10 kg of urea per mu . In the rosette period, the beginning and the middle of the ball, each time chasing the fertilizer, the application of urea 15-20 kg, combined with spraying the foliar fertilizer potassium dihydrogen phosphate and urea mixture every 10 days. Watering should be carried out in combination with topdressing. The soil in the early stage of the balling is dry and wet, and the soil is kept moist during the balling period. Stop watering until 10-15 days before harvest to facilitate storage
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
