Field management techniques for green pepper cultivation in open field

According to the characteristics of green pepper, warm water, hi-water, hi-fertilization and high temperature, the characteristics of leeches are easy to die, and the fat is easy to burn. There are different management requirements at different stages of the whole growth period. It is carried out in four stages.

　　 1. Management before harvesting

After the green pepper is planted, the early ground temperature is low and the root absorption capacity is weak. The “big promotion and small control” measures should be taken. That is, shallow watering, early topdressing. Diligently ploughing, light seedlings. When planting water, see dry and wet, timely cultivating, loosening soil, increasing ground temperature and promoting root growth. After 8-10 days, the second water is poured again, and deep cultivating ( about 7 cm ) is carried out . The near root is slightly shallow and deeper away from the plant to increase the permeability of the soil and increase the soil temperature. If the seedlings are yellow and the growth potential is weak, the fertilizer can be applied lightly (in combination with the second water ) . With water per acre composting human waste topdressing 500 kg or urea 7--8 kg, also called the control Miaofei. The purpose is to try to slow down the seedlings and raise the roots quickly. After the second watering, the seedlings are started, that is, the water is controlled, and the roots are developed to the depth to reach the deep roots. If the water is too much at this stage, the plants tend to be long and the fruit setting rate is lowered. The seedling period can be around a week.

In recent years, green pepper has been reduced in years, and the seedling period is too long. The sweet pepper enters the flowering stage, and its flowering fruit is related to air humidity. Therefore, timely watering after the seedlings can not only increase soil moisture, but also increase the air humidity in the field. Conducive to flowering fruit. A first layer of fruit grow to large beans, leaves and fruit plants grown simultaneously, to timely watering and fertilizer per acre composting human waste 500--1000 kilograms or (quick) urea 10--15 kg administered simultaneously with the Some phosphorus and potassium fertilizers promote the seedlings to be strong and prevent falling flowers and fruits. After fertilization, the land is timely cultivated when it sees white, improving soil permeability and improving soil fertility.

　　 2 , the management of the fruit period

During the fruit-bearing period, the temperature gradually rises, the rainfall gradually increases, and the pests and diseases occur one after another, which is the key period for determining the yield. The growth period is poor, and the management is not good in the medium term. The growth of the seedlings is stagnant, the viral disease occurs very quickly, the fruit is not hypertrophy, and the yield is rapidly decreased. When the seedlings are yellow, the seedlings are yellow and shrink, and almost no yield is obtained. In order to prevent premature aging, it is necessary to harvest the pepper in time, water it in time, maintain the soil moisture, promote the attack and fruit, and strive to seal the ridge before the high temperature season. Before the ridge is closed, the soil should be preserved and fertilized.

　　 3 , the management of high temperature rainy season

Excessive surface temperature will inhibit the normal growth of green pepper roots. Therefore, it is necessary to keep the ground moist. Watering should be carried out by means of frequent pouring and light pouring. That is, the amount of watering should not be too large, and the number of days of watering should be short, and the roots should be protected from summer, so that the plants can be restored after high temperature. The second flowering peak.

The roots of green peppers are afraid of phlegm and avoid water accumulation. During the rainy season, the water in the soil will suffocate for a few hours, and the roots of the green pepper will suffocate, and the plants will be wilted, forming a dead root. Therefore, the drainage ditch should be dredged before the rainy season to allow the rainwater to drain in time. Sudden rain on sunny days, or after a long rain, it is easy to cause soil air to decrease, causing plant wilting. Therefore, it is necessary to timely pour water after the rain, and follow the pouring to reduce soil moisture, increase soil permeability, and prevent root weakness.

　　 4 , the results of the late rejuvenation management

After the high temperature during the rainy season, 8--9 January temperature is cool, abundant sunshine, began to gradually for crop growth, is green pepper second flowering fruit during the peak period, so to strengthen the management of fertilizer to promote new branch, much fruit, increasing post-production, fertilizer can alternately with water, pouring - 2 times with water topdressing fast-acting fertilizer per acre 10--15 kg compartment 7--8 days pouring of water. It can also be applied to the decomposed dung water.

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
