When vegetables are changed, they should be turned first
Recently, when interviewed by reporters in Kangjiabangshui, a street on the Luocheng Street in Shouguang, Shandong, the local vegetable growers are changing their crops. The reporter found that many vegetable farmers in this change of time, in order to save time, do not turn the ground directly to plant loofah loofah. As everyone knows, this is very unfavorable to the growth of loofah.
First of all, it is not conducive to rooting and deep rooting before the seedlings colonize. Due to the cultivation of leeks, agricultural operations such as watering and stamping caused the soil to become hard and the permeability became poor. If you do not turn to directly plant the next leeks, it is not conducive to the expansion of the seedling roots, deep bar. Moreover, due to poor soil texture and permeability, rooting and dead trees are also prone to occur.
Secondly, it is not conducive to raising the temperature of the ground. Without turning to the ground, the soil is relatively compact, and the gap between the soil aggregate structure is small, resulting in a small soil porosity, resulting in poor heat storage capacity of the soil, which is not conducive to maintaining and increasing the ground temperature. After deep turning of the soil, the gap between the soil aggregate structure increases, and its heat storage capacity increases, which is conducive to the increase of ground temperature. Especially in the deep winter and early spring season, the increase of the ground temperature is very important for the seedlings and growth of vegetable seedlings, and should be deep-buried before planting.
Once again, it is easy to fertilize vegetables and prematurely decline in fertilization. Because Shangyu vegetables absorb a large amount of nutrients in the soil, it often causes lack of certain nutrients. Therefore, it is necessary to apply the base fertilizer again when the leeks are planted before the next planting, so as to meet the demand of nutrients for the pod vegetables. And now, after years of planting, the roots are more diseased and more serious. Biological bacterial fertilizer can be applied during soil preparation. The amount of mu is 50-80 kilograms, so as to act as a bacteriostatic agent and reduce the occurrence of root diseases. Therefore, it is recommended to fertilize the soil before planting the next leeks.
The best practice is that the entire shed is generally deep-turned once, with a depth of 30-40 cm. At the same time, it is applied to the base fertilizer. The amount of cooked chicken manure is 10-15 square meters, and the amount of biological bacterial fertilizer is 50-80 kg. Fat 100-150 kg.
