Polygonatum polygonatum is a common herb with high medicinal value and ornamental value. In the spring, the growth rate of Polygonatum polygonatum seedlings is relatively fast, so proper watering techniques are essential to ensure the healthy growth of the seedlings. However, the technical points and precautions of spring watering are not well understood by everyone. This article will introduce in detail the technical points and precautions for watering Polygonatum polygonatum seedlings in spring, so as to help growers properly manage the growth of Polygonatum polygonatum seedlings.
First, the key points of watering technology:
1.Observe soil moisture:The amount of watering of Polygonatum polygonatum seedlings in spring should be determined according to soil moisture. The first thing to do is to observe the moisture of the soil surface, if the soil surface is already dry, it means that watering is needed. Secondly, to observe the deep moisture of the soil, you can insert your finger into the soil, if you feel the soil wet, it means that there is no need to water; If the soil is felt to be dry, it needs to be watered in moderation.
2.Spray watering:The watering of Polygonatum polygonatum seedlings in spring should be carried out in the form of spraying. Spray watering can simulate natural rainfall, allowing water to penetrate evenly into the soil, which is conducive to water absorption by the roots. You can choose a watering can or a sprinkler head for spraying, pay attention to control the intensity and angle of the spray, so as to avoid scouring and damage to the yellow essence seedlings.
3.Watering at the right time:In spring, the watering of Polygonatum polygonatum seedlings should be selected at the right time. Generally speaking, morning or evening is a better time to water, avoid watering in direct sunlight at noon, so as not to evaporate too quickly. In addition, spring temperatures are cooler and water evaporates more slowly, so the interval between each watering can be slightly longer, usually once every 2-3 days.
4.Control the amount of watering:The amount of watering of Polygonatum polygonatum seedlings in spring should be controlled appropriately. Too much watering can easily lead to over-wetting of the soil, lack of oxygen in the root system, and cause diseases such as root rot. Too little watering will lead to water shortage and limited growth of Polygonatum polygonatum seedlings. In general, the amount of water per watering should be enough to keep the soil moist and avoid water accumulation. The specific amount of watering is determined according to the growth of Polygonatum polygonatum seedlings and soil characteristics, generally speaking, the amount of each watering is about 1 3 of the volume of the seedling container.
2. Precautions:
1.Prevent stagnant water:After watering the yellow essence seedlings in spring, pay attention to drainage and avoid water accumulation. Polygonatum polygonatum seedlings have high water requirements, but too much stagnant water can easily cause root rot and lead to limited plant growth. A layer of drain stone or sand can be placed at the bottom of the pot to promote the drainage of moisture.
2.Avoid water stains on the foliage:The foliage of Polygonatum polygonatum seedlings is prone to water stains in spring, especially if there is too much or improper watering. Water stains can hinder photosynthesis, affect the normal function of leaves, and easily cause the growth of germs. Therefore, when watering, try to avoid splashing water on the leaf surface, and you can use a watering can or drip irrigation for watering.
3.Pay attention to humidity control:The growth of Polygonatum polygonatum seedlings in spring requires a suitable humidity environment. Generally speaking, the temperature is low and the air humidity is low in spring, which can easily lead to the drying of the leaves of Polygonatum polygonatum seedlings. The humidity can be increased by increasing the humidity in the room, such as placing a basin of water or a wet towel. In addition, pay attention to indoor ventilation to avoid excessive humidity that can lead to the growth of germs.
4.Suitable temperature conditions:The temperature conditions of Polygonatum polygonatum seedlings should also be suitable in spring. In general, Polygonatum prefers a warm environment with a suitable growth temperature of 15-25 degrees Celsius. In the case of lower spring temperatures, you can choose to plant indoors and keep the indoor temperature stable.
5.Pest control:In spring, Polygonatum polygonatum seedlings are susceptible to some pests and diseases, such as aphids, powdery mildew, etc. It is necessary to observe the leaves and stems of seedlings in time, and once signs of pests and diseases are found, corresponding control measures should be taken in time. Organic pesticides or biological control methods can be used to avoid excessive chemical pesticides to avoid harm to Polygonatum polygonatum seedlings.
6.Pay attention to fertilization:Spring is a critical period for the growth of Polygonatum polygonatum seedlings, which requires proper nutrition**. You can choose to use organic fertilizers, such as well-rotted organic compost or fishmeal, for the right amount of fertilization. Pay attention to the timing and amount of fertilization to avoid root rot caused by excessive fertilization.
7.Regular pruning:In spring, the growth of Polygonatum polygonatum seedlings is relatively vigorous and prone to over-density. Regular pruning can promote the branching and growth of seedlings, keeping the plants healthy and beautiful. When pruning, pay attention to using sharp scissors or pruning tools to avoid harming the plants.
8.Pay attention to irrigation management:Water management of Polygonatum polygonatum seedlings in spring is also important. Keep it moderately moist and avoid being too wet or too dry. The frequency and amount of irrigation can be adjusted by observing the moisture of the soil and the leaf condition of the plants.
9.Protection from bright light:The sun is strong in spring, and the seedlings are susceptible to excessive sun exposure. You can choose to plant indoors or in semi-shaded areas, or use shade nets to block out bright light, etc.
10.Pay attention to temperature management:The temperature changes greatly in spring, and the adaptability of Polygonatum polygonatum seedlings to temperature is weak. It is necessary to pay attention to maintaining a stable temperature environment to avoid the impact of too high or too low temperature on the seedlings. The temperature can be regulated by shading, wind, or adding insulation.
11.Preventing the spread of the virus:Polygonatum seedlings are susceptible to viral infection, especially in spring when the climate is humid. It is necessary to pay attention to strengthening the prevention and control of viral diseases, regularly check whether there are abnormal spots or changes in the leaves and stems of seedlings, and deal with diseases in time if they are found.
12.Focus on grassland management:Polygonatum seedlings generally grow on grassland, and attention should be paid to the management of grassland. Keep the grass tidy and tidy, remove weeds and fallen leaves in time to avoid affecting the growth of Polygonatum polygonatum seedlings.
13.Strengthens growth regulation: Spring is a critical period for the growth of Polygonatum polygonatum seedlings, and growth regulators can be used appropriately to promote the growth and development of seedlings. However, it is necessary to pay attention to the dosage and avoid excessive use that may lead to abnormal plant growth.
In short, the planting of Polygonatum polygonatum seedlings in spring needs to pay attention to pest control, proper fertilization, regular pruning, irrigation management, prevention of strong light exposure, temperature management, prevention of virus transmission, grassland management and growth regulation. Only by considering these factors can we ensure the healthy growth and high yield of Polygonatum polygonatum seedlings.
