High-yield cultivation techniques for off-season pepper

Variety selection

Choose a late-ripening pepper variety that has strong growth potential, high temperature resistance in the early stage, strong anti-temperature resistance, strong anti-virus ability, good adaptability, fast fruit setting, concentrated results, good gloss, thick meat, dark green, and large horn shape.

Sowing at the right time

In mid-July to early August, Daejeon mu seed quantity of 100 grams. Seeds are sown into the nutrient bowl, 2-3 grains per pot , and covered with a layer of fine nutrient soil after sowing.

Shade seedling

It is best to use small arch sheds and shade nets to raise seedlings. It is also possible to use straw, bamboo curtains, etc., to add straw to the shed to raise seedlings. On rainy days, cover the shed with a film to prevent rainstorms from blasting the seedlings. After the rain, the cover will be removed. , noon cover.

Seedbed management

The nursery bed should choose a plot that has not been planted in the last season. After the seedbed is well prepared, the enemy is killed or the rice is sprayed with the soil, and then the membrane bed is covered with a film for 2-3 days to kill the underground pests. After 3 days, the film was uncovered and sown, followed by sowing. After sowing, use the Greenheng No. 1 300 times to sprinkle the seedbed. When the seedlings have 2-3 true leaves, spray the Greenheng 2 to 600-800 times to control the occurrence of the disease. Insect pests were treated with 25% fast killing 500-2000 times liquid. The seedbed should not be too dry or too wet. When the two seedlings of the pepper seedlings are true, the seedlings should be fixed early; each seedling should be kept 1 strong seedling, and the seedlings should be poured with a thin human and animal fat.

Timely transplanting

When the pepper seedling age is about 30-35 days, it should be transplanted in time from mid- August to early September . Generally , it is better to transplant the sunny day after 4 pm or on cloudy days and before rain. It is good to plant 4200-4500 plants before transplanting. Apply a fertilizer to the seedbed and take a medicine. To prevent root rot, blight, etc., used in the time shift 3000 times the root of water pouring Green Hang root station 1 with special effects.

Applying enough fertilizer to the field

The growth period and the short-term yield of the anti-season pepper are short, and the yield is mainly derived from the flowers and fruits in October , so it is essential to apply the base fertilizer. Acre applies high-quality farmyard manure 3000 kg, soil miscellaneous fertilizer 2500 kg, compound fertilizer 50 kg, cooked cake fat 150 kg, ammonium bicarbonate 100 kg, boron fertilizer 1 kg.

Daejeon management

5-6 days after planting fertilizer applied once coherent, livestock manure Mushi 1000 kg or 5 kg of urea, 15 days after transplanting into the flowering and fruit setting period, the dressing is a critical period when the plant fruit when 5-6, Apply 10 kg of urea to 50 kg of cake fertilizer or 30 kg of compound fertilizer , and spray 0.3% potassium dihydrogen phosphate every 10 days . At the same time, it is necessary to control the length of the plant, and 5 g of paclobutrazol can be used to spray the plant with 15 kg of water , but it cannot be re-sprayed. The flowers in the flowering and fruiting period should be kept moist and moist. High temperature easily lead to shattering, can be used pepper spiritual fountains, mu 6-8 grams of 60-80 kg of water spraying, promote fruit set, should not be a large amount of liquid sprayed on leaf and stem, flower and fruit of stained root when rot and blight, with green Hang 1 IRRIGATING 3000 times, in particular cropping the good control effect. Green Hang disease and anthrax with 2 600-800 times spraying, virus with a virus or a virus A K 600 times IRRIGATING or spraying; tobacco budworm, aphids Kuaishaling with 100 or 200 fenpropathrin Double prevention. At the end of October, the top of the branches was removed to promote rapid results and fruit enlargement. After 10 months, the temperature began to drop, before setting up large mid scaffolding; when the night temperature below 15 ℃ button cover insulation films; below 8 ℃, stamped with a small shed greenhouse film or scum cover plants Anti-frost. The two sides of the shed are sealed, and the two sides are ventilated in the sunny afternoon. The shed temperature is maintained at 20 °C -25 °C during the day and 8-10 ° C at night . After November , the greenhouse is mainly dry.

Pepper general-season in mid-October on the market as early as the October 1 after the listing. As long as we grasp the insulation and disease prevention and preservation technology in the greenhouse, we can receive 1000-1500 kg per mu before and after the New Year's Day .

 

Flat Field Holographic Concave Grating

The Concave Grating has the advantage of being able to constitute a spectroscopic system without any assistance from concave mirrors or similar types of image-forming elements. For this reason,the Concave Grating is used in a wide range of applications, such as analytical instruments,optical communications,biotechnology,and medical instruments. Spectroscopes incorporating concave gratings are classified roughly into two groups: polychromators or monochromators.
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
