How to grow buckwheat head

Buckwheat head, also known as Jiantou, botanical name, belongs to the perennial root herb of Liliaceae. It has been cultivated in China for 3000-4000 years since ancient times. Today we will talk about how to grow buckwheat heads.

First, sowing seeds

The suitable planting period is early September, and the planting methods are clear seed and interplanting.

2. Planting density

The row spacing is 20-25cm × 10-15cm. Ploughing and preparing the soil before planting, applying rotten stable fertilizer as base fertilizer, applying 2500kg, calcium superphosphate 25-30kg and potassium chloride 5-7.5kg, or ternary compound fertilizer 30kg. Make 1.2mi 1.5m wide beds, drill holes or dig planting ditches, sow balls in neat shape, medium size, free from diseases and insect pests, 75-100kg seeds used for 667m2, one seed balls for each hole, and covered with charred mud. In order to prevent the buckwheat head from showing turquoise and the taste becoming bitter, when planting, the seed ball is obliquely planted in the planting ditch and then grows into a plant. There is a curved neck between the buckwheat head and the leaves, so that the buckwheat head will not be exposed to the soil surface by Rain Water. Ensure that the buckwheat head is white and not bitter. Buckwheat grows slowly during the year and can be interplanted with other crops with short growth periods.

III. Field management

It was germinated and unearthed 10 days after planting, and after emergence, the seedlings were ploughed and weeded, light fertilizer was applied frequently, and the feces and urine of mature people were applied twice. Overwintering fertilizer was applied once a year, organic fertilizer was applied between rows, 667 1500kg. When the weather turned warm in spring, urea 10-15kg was applied to 667 years to promote the growth of seedlings. In April, 667m2 applied ternary compound fertilizer 15kg, and the middle of May was the expansion period of buckwheat head. Topdressing urea 7.5-10kg, potassium chloride 7.5kg or ternary compound fertilizer 25kg should be applied again in mid-May. After each topdressing, it is combined with ploughing and weeding to cultivate the soil to ensure the whiteness of buckwheat head. Plant growth gradually decline, can be carried out bundle leaves, to promote bulb hypertrophy, half a month before harvest, not prematurely.

IV. Pest control

Buckwheat head is more resistant to disease, but there is downy mildew in old producing areas, which can be controlled by disinfectant alum or ethyl phosphorus aluminum manganese zinc. Rust can be prevented with strychnine. Virus diseases can be prevented and treated with plant disease spirit or virus A. Insect pests have thrips, which can be controlled by killing. Aphids can be used once to control aphids. When the leaves turned yellow in mid-June, they were collected and listed on the market.
