Drip and fertilization management:

After the drip irrigation technique under the membrane, the growth of the pepper is completed by drip irrigation, and the applied fertilizer is applied with the water droplets, the water and fertilizer are synchronized, “eat less meals”, and the water and nutrient needs are required according to different development stages of the pepper. Reasonable supply to achieve high production goals.

Drip and fertilization management: When using drip irrigation system for fertilization with water, first calculate the amount of fertilization according to the area of ​​ferro-irrigation and the amount of fertilization per mu; fertilize 30-45 minutes after the normal drip irrigation in fertilization area; before the end of drip in this round of irrigation Close the fertilization tank ball valve for half an hour; the solid particles of fertilizer injected into the fertiliser tank should not exceed two-thirds of the total volume of the tank; adjust the gate valve on the first outlet and the inlet to increase the pressure difference between the front and the back by 0.05Mpa. . The dripping time and fertilization time are determined according to the characteristics of pepper growth, mainly in seedling stage, flowering stage, fruit setting period, fruit expansion period and maturity stage.

Emergence water. After sowing, the seedling water can be dripped according to the soil moisture. If the soil moisture is poor, the seedlings can not be satisfied. The drip can be 12-15 square meters per acre. For the better moisture, the seedling water can be dripped.

Seedling to early flowering. The pepper needs less water from the seedling stage to the early flowering stage, and the water is dripped twice.

The fruit is inflated. The expansion period of capsicum fruit is the period in which the water and fertilizer are most needed in a lifetime.

Fruit ripening period. The temperature of the fruit gradually decreased during the ripening period, and the water requirement of the pepper decreased gradually.

Drip irrigation tape  features:

1. The effluent is uniform and the uniformity of effluent can reach more than 85%.

2, the dripper has a self-filtering window, anti-blocking performance is good.

3, the use of labyrinth flow channels, with a certain pressure compensation.

4, the spacing of the dripper can be determined according to user requirements.

5, can be bent around the bend, easy to operate.

6. Easy to install and use, low manual installation cost, light weight and convenient transportation. Drip belt model and specifications

Inner diameter 16mm Wall thickness 0.2-0.4mm Spacing 150mm, 200mm, 300mm Flow rate 2-3L/H.

Chili is warm, hi-water, and hi-fertilizer, but it is easy to get sick at high temperature. The leeches are easy to die, and the fat is easy to burn. Different management requirements are required at different stages of the whole growth period. After harvesting, it is necessary to promote roots and promote sputum before harvesting; start harvesting to fruiting period to promote cockroaches and attack fruit; Loss and death; in the end, we must continue to strengthen management, increase production and income. I would like to introduce you to the fertigation technology of pepper:

Water Saving Irrigation

When irrigating the pepper, the valve on the fertiliser should be closed, the control valve of the drip irrigation system branch pipe should be fully opened, and then the irrigation should be carried out according to the micro irrigation scheme. Turn off the power at the end of the irrigation and immediately close the control valve. The drip irrigation wet depth is generally 30cm. The principle of drip irrigation is a small number of times, do not extend the drip irrigation time to achieve the purpose of multi-irrigation.

 

The fertilizer is first dissolved in water, and in some cases the fertilizer is dissolved in water one day before fertilization. When fertilizing, use the gauze to filter and transfer the fertilizer into the differential pressure fertilization tank; or pour into the gravity fertilization tank; or in the open container with a venturi fertiliser. The two methods of fertilization are described below.

Connect the fertiliser tank in parallel with the pressure regulating valve on the main pipe, and the inlet pipe of the fertilizer tank should reach the bottom of the tank. Before fertilizing, first fill the water for 20-30min. When fertilizing, tighten the tank lid and open the inlet valve of the tank. After filling the tank with water, open the outlet valve of the tank to adjust the pressure difference to keep the fertilization speed normal. Fertilization time is generally controlled at 40-60min to prevent uneven or insufficient fertilization.

2. Venturi fertilization method

Parallel the venturi with the valve of the main pipe, filter the previously dissolved fertilizer, pour it into the open container, and put the tip of the venturi into the fertilizer. The tip should have a filter, the tip. Do not put it on the bottom of the container. Open the valve on the suction pipe and adjust the valve on the main pipe to make the suction pipe absorb the fertilizer evenly and stably.
