The pattern of pre-harvest pepper seedlings and wheat harvesting after harvest is called wheat bran. This model not only saves a lot of time, but also increases the economic income of farmers. Let's talk about the high-yield and high-efficiency cultivation techniques of wheat bran.
First, the variety selection
The cultivation of wheat bran should be selected from heat-resistant and moisture-tolerant varieties. The varieties available in the northern region are mainly early-ripening pepper hybrids such as Baojiao No.10 and No.11.
Second, nursery
1. Sowing period
According to the wheat harvest period, the pepper planting period is pushed forward for 60 days to calculate the seeding and seedling period. Generally, the seedlings are planted at the end of March to the beginning of April, the seedling age is 55-60 days, and it is planted to the wheat field before and after June 10.
2, floating seedlings
Construction of nursery plastic greenhouses, and then laying nursery ponds according to the planting area of ​​peppers, generally according to the design of nurses with 67,500-7.5 million plants per acre. After the nursery ponds are built, prevent the floating seedling trays from floating seedlings before the water in the seedling trays. A kilogram of nutrient solution is provided. 1-2 coated seeds were planted in each nursery hole with a seeding depth of 5-10 mm. A method of first sowning the back cover substrate is used, and after the seeding is finished, a 1-2 mm thick substrate is sprinkled on the surface of the seed.
3. Seedling management
The principle of floating seedling water management is “first less and then moreâ€. From sowing to the big cross, the general water depth is controlled at 5-6 cm. The temperature of the true leaves of the pepper seedlings is gradually increased. The water depth in the nutrition pond can be increased to 8-10 cm. In principle, the seedlings are flushed. The depth of the pool water is just right; in the case of 4-5 true leaves, the second fertilization is carried out according to each seedling tray plus 20 g of floating seedling special fertilizer, and the potassium dihydrogen phosphate and urea mixture is sprayed on the seedlings according to the growth of the seedlings. Supplemental nutrition promotes the healthy growth of pepper seedlings, and the spraying time is 7-10 days. In order to prevent the production of green algae, add 1 g of copper sulfate per seedling tray, and drive evenly into the nursery pond at 5 o'clock and mix well; before the emergence and seedling period, according to the weather and temperature, the temperature of the surface of the nursery tray should be kept at 20 -25 ° C.
Third, the soil preparation
The cultivation of wheat bran peppers should be highlighted early, and it is necessary to make strong early mechanical harvesting, early land preparation, early ridge mulching, and early four-zone planting. It can be applied to ternary compound fertilizer 750 kg per mu plus urea 300 kg per mu, 1.2 m belt type ridge coating.
Fourth, colonization
Each ridge is planted with 2 rows of narrow rows and plants, wide rows of 70 cm and narrow rows of 50 cm with a plant spacing of 33 cm. The triangles are staggered and planted, and the plants are planted in time.
V. Field management
The temperature of the wheat bran pepper is higher when it is planted. It basically does not slow down the seedlings and grows fast. It is necessary to promote the plant and seal the plants before the hot weather in July. Therefore, it is necessary to timely pour the water to the seedlings. The amount of water should be increased during the flowering period, and the pepper should be drained in time after the rain. The principle of fertilization is to apply the seedling fertilizer once after the slow seedling, apply 150 kg per mu of urea; after the fruit, chase 1 time Peng fruit fertilizer, apply compound fertilizer 225-300 kg per mu. Before and after the beginning of autumn, the fruiting season is entered, and the compound fertilizer is applied at 300 kg per mu to prevent premature aging and increase production. Each fertilization should be carried out in conjunction with watering. In the early stage of planting, cultivating and promoting rooting, the first time after the door pepper was seated, the second time, in the middle of July, the pillar ridge can be used for the second time.
Sixth, harvest
Harvested according to market conditions and fruit size. Timely harvesting or affecting later fruit growth. Late harvesting in the late autumn season or silage preservation after harvesting can not only increase the selling price, but also increase economic benefits.
The above is the high-yield and high-efficiency cultivation technology of wheat bran, the content is for reference only. Xiao Bian warmly reminds that pepper cultivation should be carried out according to local conditions.
