Buckwheat high-yield planting technology Fertilization and watering management of common pests and diseases, buckwheat is one of the precious biodiversity resources of human beings, native to South America, the only whole-plant protein grain, the only monomer plant can meet human basics Nutritional food, its high market price and strict requirements on soil, climate, water and fertilizer conditions, is known as super grain and Inca gold, let's take a look at the high-yield planting techniques of buckwheat!
Growth conditions The growth conditions of buckwheat include soil, soil pH, climate, water, rainfall, temperature, radiation and altitude. The suitable temperature is 15-20 °C, the maximum temperature is not more than 32 °C, and the altitude is above 1500 m. The soil pH is 5.5-8.5, and the soil moisture is at least 3/4 of the field water holding capacity to promote seed germination.
Production materials for planting and preparing buckwheat include seed, compound fertilizer, planter, etc. Rotating the land one week before planting should not be too deep, it is best to use a ball press. Fertilization 40 kg / mu, the best farmyard fertilizer, compound fertilizer (N: P: K each 15%). However, it is not possible to use hibiscus for sowing because it is difficult to control the uniformity of the depth.
The sowing time for timely sowing of buckwheat is from the beginning of May to the end of May. The selection of seeds with a rainfall of about 30 mm is beneficial to seed emergence, and 400 grams of buckwheat per acre is mixed with 1.4 kg of fried millet. Use a small two-legged grain seeder to adjust the seeding depth and seeding volume before sowing. The sowing depth is 1-2 cm, the row spacing is 50 cm, and the plant spacing is 30 cm.
Seedling management buckwheat germination about 3 days after sowing, 5 days unearthed, such as 10 days without emergence should be replanted in time. At the stage of emergence, attention should be paid to underground pests. If the front is a potato, it is necessary to prevent wild boars. Buckwheat is planted for about 30 to 40 days, and the seedling grows to 15 to 20 cm to start weeding.
In the field management, buckwheat should be artificially weeded, and herbicides should not be used. The first weeding and intercropping should ensure the plant spacing, the plant spacing is 20-30 cm, leaving a single seedling, and the row spacing is 45-50 cm. During the second weeding, the roots can be cultivated to promote root growth and prevent late lodging. 40 kg of compound fertilizer per mu, in principle, no top dressing, but when the soil fertility is too poor, consider topdressing. When the soil is dry when there are irrigation conditions, it can be irrigated for 40 to 70 days.
The harvested buckwheat is harvested when it is grown for 100 to 130 days. When ripe, the seeds become hard and the nails do not move. Prepare plastic sheeting before receiving the goods (for covering, threshing and drying when the weather is not good, use the paving), and use the sickle to collect it in the mountainous area and harvest it on sunny days. After the harvest, the weather is fine, and it can be bundled into small bundles for dehydration. After threshing, it should be aired in time to avoid fermentation deterioration. After drying and drying, fan out the impurities in the buckwheat and sell it.
