How to Prevent Vegetable Seedling Death? Latest Measures Explained
In the process of production and cultivation, vegetable seedling death often occurs, seriously affecting the growth of vegetables. There are also many causes of vegetable seedling death, so in order to deal with vegetable seedling death, what should we do during cultivation? Follow the editor to take a look.
1. Microbial fertilizer prevents diseases and pests
Before vegetable cultivation, the greenhouse and vegetable garden soil must first be prepared. In recent years, soil-borne diseases have become increasingly serious. In order to prevent the occurrence of diseases, in addition to plowing the land and applying microbial fertilizer and dipping roots in chemicals, it is also often necessary to adopt the method of applying chemicals or microbial fertilizer in holes to promote roots and prevent diseases. When vegetables have just been transplanted, underground pests like to gnaw on the roots, causing the aboveground seedlings to wither and, in severe cases, die. Biological microbial fertilizer can not only provide fertility for vegetable growth, but also add beneficial bacteria to prevent soil-borne diseases, while also improving the stress resistance and lodging resistance of vegetables.
2. Organic fertilizer prevents fertilizer damage
Excessive application of chemical fertilizers, overly concentrated application, or the single application of a certain chemical fertilizer will greatly increase the occurrence of fertilizer damage, causing root burn and seedling burn, leading to vegetable seedling death and plant death. Therefore, in order to prevent fertilizer damage, it is necessary to reduce the amount of chemical fertilizer applied and increase the application of biological microbial fertilizer and organic fertilizer. However, it should be noted that organic fertilizer must be fully decomposed, otherwise it will also cause fertilizer damage. Especially when using farmyard manure such as chicken manure and duck manure as base fertilizer, it must first be subjected to high-temperature greenhouse sealing so that it is fully decomposed before use.
3. Planting depth
Vegetable seedling death due to disease occurs from time to time, mainly because of stem rot and phytophthora blight. After vegetables are transplanted, this often occurs and is closely related to planting depth. If vegetables are planted too deep, the base of the seedling stem is buried in the soil, and in the early stage there is relatively little of it. When the outside temperature is too high, water evaporates quickly, causing the temperature at the base of the stem to become too high. The epidermal tissue at the base of the stem is damaged, creating favorable conditions for pathogens. Therefore, when transplanting vegetables, be sure to pay attention to suitable depth, and the best solution is ridge cultivation.
4. Water appropriately
Too much watering will cause root suffocation. In addition, water temperature also has a direct impact on the physiological activity of the root system. If the difference between soil temperature and water temperature exceeds 5 degrees, then after watering it will cause a sudden change in soil temperature and damage the root system, instead affecting the root system's absorption of water and causing physiological drought. Therefore, it is best to irrigate when the water temperature and soil temperature are close. In autumn and winter, it is best to first store the water indoors for a period of time, or add warm water, so that the water temperature rises to 15-20 degrees before irrigating. The watering time is generally at 10 a.m. and after 4 p.m. Remember never to water at night, as this will increase the chance of disease infection and cold damage.
