In early spring, after the planting of vegetables, the temperature is still low, and the environment is harsh, which brings a big test to the management of vegetable seedlings. How to increase the temperature of the ground, regulate the temperature of the greenhouse, promote the down-rooting of the plant roots, and make the rapid seedling reduction of vegetables become the key to the cultivation of strong trees. There are some problems commonly encountered by vegetable farmers in the management of seedlings. Here are some suggestions on how to manage cucumbers, tomatoes, and peppers after planting.
Cucumber should promote control
First of all, to properly reduce the night temperature, in the sunny days can not put a floating membrane, reduce the greenhouse insulation, while appropriate late grass hay.
Second, cover the white mulch to increase the ground temperature and reduce the humidity in the shed. Watering is strictly controlled at low temperatures, and the amount of watering and the frequency of watering can be flexibly determined based on plant growth, weather conditions, and dry soil moisture.
Again, apply fertilizer properly. After planting, the cucumber has less hairy roots, and its ability to absorb nutrients is weak. It is recommended that the vegetable grower should mainly support roots and leaves, and fertilizers such as amino acids and chitin can be applied to promote capillary root growth, and at the same time, foliar fertilizer can be used to spray leaves. , promote plant development.
Tomato should be controlled
If irrigation is done before planting, it is not necessary to water immediately after planting. If there is no irrigation before planting, the soil moisture content is insufficient. After planting, water can be applied between the small rows under the membrane. But pay attention to the amount of irrigation can not be too large, in order to infiltrate the soil layer of soil is appropriate. After 4-7 days of planting, the seedlings should be lightly watered. Do not delay as much as possible because the young seedlings need to grow new roots quickly. Large soil moisture should be maintained. In particular, sand should pay attention to watering. After the seedlings were watered, the seedlings were planted and the cultivator was strengthened 2-3 times. The seedlings should be moderate, when the plants show short thick stems, dark green top leaves, wrinkled leaves, the proportion of flower and fruit coordination, and the first spike fruit when the end of the seedlings.
Sweet peppers should be credited to keep flowers
Sweet pepper flower bud differentiation period in the event of continuous rainy weather, will result in serious drop flower drop. Therefore, when planting sweet peppers, the vegetable grower should pay attention to the light in the early stage and promote plant flowering and fruit setting. Various measures can be taken to increase the light intensity and time as much as possible: under the premise of heat preservation, the grass cover will cover the cover as early as possible to maintain the light transmittance of the cover film; reasonably close planting, pruning and binding the vine; The curtain adds light. For poor flowering and fruit setting plants, naphthalene acetic acid may be sprayed appropriately at a concentration of 3010-6 to promote fruit setting.
Aspirin [Aspirin, 2-(acetoxy) benzoic acid, also known as acetylsalicylic acid] is a white crystal or crystalline powder, odorless or slightly acetic acid odor, slightly soluble in water, easily soluble in ethanol, can be Soluble in ether and chloroform, the aqueous solution is acidic. This product is a derivative of salicylic acid. After nearly a hundred years of clinical application, it has been proved that it has a good effect on relieving mild or moderate pain, such as toothache, headache, neuralgia, muscle pain and dysmenorrhea. It is also used for colds, flu, etc. Relieving fever of febrile diseases, treating rheumatism and so on. In recent years, it has been found that aspirin has an inhibitory effect on platelet aggregation and can prevent thrombosis. It is clinically used to prevent transient ischemic attack, myocardial infarction, artificial heart valve and venous fistula or other postoperative thrombosis.
