Yangchun March tube greenhouse focus on good soil fertilizer
Core Tip: In the spring of March, the greenhouse recovers. At this time, with the gradual increase in temperature, greenhouse management has also entered an important period. It is well-known that greenhouse crops grow under the protection of greenhouse films and rely more on soil and fertilizer, good soil environment, adequate nutrient supply, and appropriate moisture and moisture. It is an important guarantee for healthy growth of crops in greenhouses. Many people know the importance of the management of "soil and soil water" in greenhouses, but they are still not in place in practical operation. This edition of Xiaobian combined with the production needs in the shed, and talked to you about the "soil and water" thing. Soil strict control acid and alkali soil "change color" Many growers say that there is a problem with “earth†in the process of growing greenhouses. Even after some new sheds are planted for 2 to 3 years or even 1 year, moss and red moss appear on the soil. In fact, the acidification of soil will cause the decrease of soil pH. The salinization of soil will increase the salt content of greenhouse soil. The eutrophication of soil is suitable for some algae to survive. When the soil surface is dry, the algae will die, and the red algae will show red. These phenomena are the key to the problem of greenhouse soil. In order to reduce and change the redness and greenness of the soil surface, the following measures should generally be adopted: 1. The modifiers used should not increase soil nutrients (mainly N, P, and K nutrients) as much as possible, and can regulate the acid-base balance of the soil. 2. The use of organic substances, through the chelation of organic substances, increases the mobility of soil salt segregants, reduces the concentration of salt in the soil, and resolves the discoloration of soil surface from the source. 3. It is suggested that farmers should use drip irrigation in greenhouses, and flood irrigation must pay attention to the permeability of soil, reduce soil moisture, deepen the soil, and break the bottom of the plow. 4, basal fertilizer must be applied with organic fertilizer, preferably bio-organic fertilizer or bacterial fertilizer agent. We must be sure what to do with organic fertilizers, such as organic fertilizers for dead animals and plants, manure organic fertilizers, and straw waste organic fertilizers. Although other organic fertilizers have a high determination of organic matter, they only increase organic matter when measured, such as raw materials. Lignite organic fertilizer, organic fertilizer with furfural slag as raw material This is a stable carbon, which is not effective for soil improvement. Fertilizer-controlled nitrogen with main application "organic" The demand for chemical fertilizers in spring greenhouse crops is not the same, but the fertilization methods for different vegetables are also different. When fertilizing we must first determine the characteristics of the soil and then fertilize it so that the nutrients needed by the vegetables can be reasonably determined. Control the amount of nitrogen fertilizer to reduce the amount of nitrogen fertilizer application, it should be based on the amount of fertilizer required by different vegetables, generally 10 ~ 12 kg of pure nitrogen per acre is appropriate; nitrogen fertilizer should be deep, and with phosphorus, potassium fertilizer application or application of three Yuan compound fertilizer should be timely covered with soil after application. It is best to use chemical fertilizers to infiltrate or combine with drip irrigation under the membrane to reduce the loss, increase the utilization rate, and stop the top dressing 20 days before harvest. The implementation of formula fertilization according to the characteristics of the needs of different vegetables and soil fertilizer conditions, determine the appropriate amount of nitrogen, phosphorus, potassium and trace elements and the corresponding fertilization techniques. The maximum period of demand for nitrogen, phosphorus and potassium in greenhouse vegetables was: cucumbers were grown for 75 to 140 days after planting, tomatoes were for 30 to 52 days, and sweet peppers were for 30 to 60 days. Although the amount of trace elements required by other vegetables is extremely small, it is indispensable. For the use of micro-fertilizer foliar sprays, good dosage standards should be used. Ecological Organic Fertilizer Application The organic matter content of organic fertilizer can reach 45%. It can act as a nitrogen-fixing, phosphorus-release, and potassium-releasing agent for vegetables, and can also decompose residues of pesticides and chemical fertilizers. In the spring, summer and autumn, it can be matured in 5 to 6 days, and in winter it takes 7 to 10 days to mature. Generally, the reactor is heated for 1 to 3 days and the temperature in the reactor rises to 80°C. It kills E. coli and eggs and eliminates the smell of chicken manure. After the compost becomes loose and dry, covered with white hyphae, it can be issued in two days. Kind of mellow flavor. Look at the water and combine it with the “actual†Reasonable watering of shed vegetables is an important measure to increase production. Watering vegetables in greenhouses depends on the circumstances and the actual situation, so as to ensure the harvest of vegetables in greenhouses. First, the water should not be too large, at low temperatures, the corresponding reduction in the amount of water, the amount of watering should be small, the interval can be appropriate longer, avoid flooding flooding, so as not to cause low temperature and humidity caused the roots of vegetables. Second, the time should be appropriate. Watering vegetables in spring should be arranged before and after noon, before 10am and before 3pm, when the temperature of the greenhouse is higher, and the side effects after watering are the least. Try to avoid watering in the early morning and early evening. In case of causing freezing damage to vegetables. Third, depending on the weather conditions, sunny days should be properly poured, and the cloudy days should be less or no. The wind and rain should not be watered to ensure normal greenhouse temperature. Fourth, watering should focus on the large amount of evaporation of soil moisture in the southern part of the greenhouse, and the amount of watering can be appropriately increased. The temperature on the east and west sides of the greenhouse is low, and the sunshine duration is also short. The amount of watering should be appropriately less.
Introduction Of Baby Monitor
Monitoring equipment

The baby monitor, also known as baby monitor or baby monitor, is a wireless family safety protection system. It is composed of two parts: a carer (also known as the monitoring terminal or baby terminal) and a monitor (also known as the control terminal or parent terminal). By placing a carer in Baobao's room, you can monitor the safety of the baby at any time through the monitor. As a family security product, the baby monitor provides real-time monitoring by using the monitoring terminal's every move, every word and every action of the baby. The monitoring results are sent to the control terminal equipment in the hands of the supervisor through the radio waves of analog signals or digital signals, and are restored to video or audio. By using the baby monitor, parents or guardians no longer need to stay close to the baby or child to know their behaviors, avoid frequent checks that affect the baby's rest, and can immediately detect and deal with abnormal situations when they occur. The baby monitor is not only the best daily care product for infants and young children, but also a necessary good helper for caring for the elderly and patients.
The baby monitor greatly improves the freedom and flexibility of parents' life. With this device, parents can handle other affairs in other rooms or even outdoor courtyards. At the same time, they also know the situation of their children very well, so they don't have to worry all the time, making the baby monitor a good helper for parents. L In addition to baby monitoring, baby monitors are widely used for elderly care and safety protection in supermarkets, offices, companies, schools, families, hospitals and other small places.
