When building greenhouses, in order to save time and effort, the mellow soil on the surface layer is generally used to build the shed walls, so that the soil used for planting vegetables is mostly raw soil about 1.5 meters from the surface, which lacks organic matter. Therefore, a large amount of organic fertilizer is needed.

1. Increase the application amount of manure such as chicken manure.

Newly built sheds are mostly raw soil and lack of organic matter. Therefore, a large amount of organic fertilizer should be supplemented. Organic fertilizers such as rice husk manure and chicken manure can increase the amount per mu to about 35 cubic meters. After the application of these organic fertilizers, the soil cannot be increased rapidly. In the organic matter, it can improve the physical and chemical properties of the soil to a certain extent.

2. Increase application of biological fertilizer.

In the newly built greenhouse, the content of various microorganisms in the soil is low. Even if a large amount of organic fertilizers such as chicken manure and rice husk manure are applied, the organic fertilizer cannot be quickly decomposed into soil organic matter due to the lack of microorganisms in the soil. Therefore, when vegetable farmers apply organic fertilizers such as rice husk manure and chicken manure to the newly built greenhouse soil, they must pay attention to increasing the application of biological bacterial fertilizer, such as applying 40 to 70 kg of biological bacterial fertilizer per acre to quickly replenish the microorganisms in the soil.

3. Increase the application of commercial organic fertilizers.

Commercial organic fertilizer has high organic matter content, which helps the soil quickly replenish organic matter after use. Vegetable farmers can apply manure to the soil of the new greenhouse for the first time, combined with the application of commercial organic fertilizer, and apply about 500 kg per mu, which can ensure the nutrients needed for the early stage of vegetable growth.

4. Supplement nitrogen, phosphorus and potassium fertilizers.

The soil in the new greenhouse is raw soil, and the content of nitrogen, phosphorus and potassium in the soil is extremely low, so when applying base fertilizer, you must pay attention to increasing the application of nitrogen, phosphorus, and potassium fertilizers. Generally, about 50 kg of chemical fertilizer is used per mu.

5. Supplement medium and trace elements.

For vegetables to grow healthily, they need not only nitrogen, phosphorus, potassium and other large elements, but also more than 10 medium and trace elements such as calcium, iron, and boron. The lack of medium and trace elements in the soil of newly-built greenhouses has become a prominent problem restricting the high yield and quality of vegetables.

Chairs & Sofas For Elderly

Professional aging products are based on "knowing the old and understanding the old". The design of aging products should meet the real needs of the elderly, facilitate the care needs of nursing staff, and adapt to the home-based elderly care environment.
The characteristics of the elderly are aging of the lumbar spine, discomfort of the cervical spine, osteoporosis, and fatigue. Therefore, it is particularly important for the elderly to protect the waist and neck to delay the aging rate and reduce the incidence of diseases and accidents.
First, the backrest of the Chair is large and strong, and it is equipped with armrests, so that the waist of the old man is close to the back of the chair and can support the head and shoulders of the old man.
Second, the height of the chair should be at the same level as the knee, that is, when the old man is sitting, his feet can be placed flat on the ground. At the same time, the length of the chair seat should be the same as the length of the old man's hip to knee, so that the knee joint can be maintained at about 90 degrees, and the ankle joint can be in a natural drooping rest state.

Third, the chair should have some weight, and 3-4 kg is the best. If it is too light, it is difficult to maintain certain stability and easy to slip. The chair material should not be too soft.
