Take care when taking the seedlings to reduce the wound
At present, most of the nursery use nursery nurseries or trays, and the seedlings are not noticed, and it is easy to cause damage to the roots and stems. It is recommended that the vegetable farmers can use their fingers to top the bottom of the nutrient bowl or pinch the bottom of the tray before taking the seedlings, and then take out the seedlings. In this way, the plug or nursery seedling can be detached from the seedling substrate and root system in advance, and the seedlings do not need to use too much force, which greatly reduces the chance of root and stem injury.
Planting is not planted, deep anti-high temperature burns
In order to promote the rapid rooting and slowing of seedlings in the early stage of planting, the amount of water for planting water and slow seedling water is very large. Once the planting is too deep, the base of the vegetable stem is buried in the soil, and the excessive watering, the external temperature is high, causing the water vapor to volatilize upwards, the temperature of the base of the stem is very high, and it is easy to burn the base of the stem, which is conducive to the infection of the disease. Remind the vegetable growers that ridge planting can be used in the sheds with high groundwater level, soil viscosity, and soil-borne diseases. In the sheds where the above situation occurs, the cultivating method is adopted. Summer vegetables are not recommended for colonization to the bottom of the ditch or for deep planting.
Watering, avoiding wetness, avoiding cracks
In the high temperature season in summer, the plants are easy to grow. Some vegetable farmers use water control methods to suppress the growth of the plants. Once the water is poured, the water content in the cells suddenly rises, which will lead to the emergence of cracked stalks. It is recommended that small waters be poured and timed. In the usual management, plant growth regulators can be sprayed to increase the toughness of the stem and reduce the occurrence of cracked stalks. After the stalk occurs, spray the drug early.
Insect prevention work to avoid pest bites early
When summer vegetables are planted, the high temperature period is high. Many vegetable pests, such as whitefly, aphids and thrips, are on the rise, which poses a great threat to seedling growth. The pores formed by pests and sputum are important ways of bacterial infection, so it is necessary to do a good job in pest control. When receiving the seedlings, the vegetable farmers should pay attention to check whether the seedlings carry pests and eggs, and do a good job in the prevention and control of seedlings to avoid the insects entering the shed.
The insect net should be installed early before the seedlings have been planted. Do not wait until the seedlings are planted. After the vegetable is planted, it is necessary to pay attention to observe the growth state of the vegetables at any time, and timely discover the symptoms of the pests in the early stage, and timely targeted spray prevention.
