Artemisia oleracea, spinach, cilantro and other leafy vegetables are all broadcast lively and do not need to be transplanted. In general, vegetable growers are required to ensure the foolproofness and large seeding rate. The vegetable grower must perform the seedlings after the seedlings grow, so as to ensure the plant's There is enough room for growth to prevent poor growth due to plant closures that cause field closure.
As garland chrysanthemum, because vegetable growers are mainly based on sowing, many vegetable farmers believe that increasing the number of plants grown can increase yield, so the time between the seedlings is relatively small, and the seedlings are often placed at a spacing of 2 cm square. However, such a density makes it easy to make fields closed in the middle of growth, and the air permeability is poor, the stalks are weak, and lodging is also easy to occur. Because the distance between the plants is very small, as long as one place appears lodging, it will easily cause a large area of ​​lodging. Therefore, such a density of seedlings not only fails to increase the yield, but also reduces the yield, and many plants fail to meet the requirements of acquisition standards, which reduces the benefits. According to the vegetable farmer Dong Guangde, he usually conducts seedlings in a 2.5-3 cm row spacing, so that the plant spacing is increased, ventilation and light transmission are enhanced, and the potential for high yield per plant is fully utilized. Such plant growth is robust and resistant to lodging. , thus ensuring to increase the overall output. Because communis could not be ploughed after sorghum was sowed, vegetable farmers would also remove the weeds while they were in the field.
Speaking of spinach, the vegetable growers usually sow at a spacing of 8-10 centimeters, but in some rows, the seedlings are better and have higher density, which is also not conducive to the growth of spinach, and can be 2 cm in accordance with the spacing of the plants. When performing the thinning, when the young plants are used, strong seedlings should be used to grow the weakly growing plants. The same time, the seedlings can also play the role of shallow cultivator. If there is a large area of ​​plots without seedlings, the seedlings can be reduced at the two ends of the plot, leaving 2-3 more, which will reduce the losses caused by empty plots.
