First, strengthen the refining seedlings
10-15 days before planting, it is necessary to strengthen ventilation and exercise seedlings. Grasshoppers must be exposed as soon as possible, and at night they must be left open until they are removed.
Second, spray fertilizer drugs
Before starting planting, fat medicine can save liquid medicine, prevent and cure pests, and play a role in strengthening seedlings. Deltamethrin can be used to control aphids, chlorothalonil, carbendazim and other diseases. Leaf fertilizer can be potassium dihydrogen phosphate, urea 0.2% solution, spray alone or mixed.
Third, timely planting
According to the local climate, seize the "cold tail warmer" planted on time. After such planting, you may encounter several good sunny days. The seedlings can quickly grow new roots and restore seedlings, restore growth, and benefit from early maturation.
Fourth, protect the root system
Watering the day before raising seedlings and cutting seedlings the next day. Generally speaking, the bandits must be 2.5-3 inches square and 3 inches high. The seedlings should be grasped in such a way that they are less likely to injure their roots and should not be dispelled. The seedlings from the day must be transplanted on the same day.
V. Suitable for deep planting
Roots and deep plants such as eggplant and tomato should be planted deeply, and cotyledon should be buried. Shallow root plants such as pepper and cucumber should be planted in shallow depth, with soil and ground flat, and cotyledons on the ground. Planted deep, easy and stiff seedlings, planted too shallow and easily frozen.
Six, prevent freezing
In case of cold currents, it is necessary to prevent freezing damage by watering or irrigating to prevent freezing or reduce frost damage.
Seven, pay attention to watering
After the transplanting seedlings are completed, the transplanted seedlings must be irrigated once in a row, which is beneficial to easing seedlings, promoting early rooting of seedlings, shortening the time for seedlings to grow, and shortening the time to market for vegetables.
Welding mask is a type of headgear used when performing certain types of welding to protect the eyes, faceandneck from flash burn, ultraviolet light, sparks, infrared light, and heat.
welding
masks are most commonly used with arc welding processes such as
shielded metal arc welding, gas tungsten arc welding, and gas metal arc
welding. They are necessary to prevent arc eye, a painful condition
where the cornea is inflamed. welding masks can also prevent retina
burns, which can lead to a loss of vision. Both conditions are caused by
unprotected exposure to the highly concentrated ultraviolet and
infrared rays emitted by the welding arc. Ultraviolet emissions from the
welding arc can also damage uncovered skin, causing a sunburn-like
condition in a relatively short period of welding.
