Sweet buckwheat, the amount of seed per acre of land for 2.5-3kg. buckwheat, the amount of seed per acre of land for 1.5-2kg. planting methods: 1, land preparation, deep plowing and deep tilling of 20cm, per acre of land to apply 2,000kg of organic fertilizer, 25kg of phosphorus fertilizer, 10kg of potash fertilizer. 2, sowing, planting spacing of 35-50cm, the depth of sowing 3-4cm, the amount of seed per acre of 2.5-3kg or so. 4cm, the amount of seed per mu is about 2.5-3kg.

A buckwheat acre how much seed

1, buckwheat seed amount and soil fertility, buckwheat varieties, seed germination rate, sowing method. If it is sweet buckwheat, the amount of seed per acre is about 2.5-3kg. If it is buckwheat, the amount of seed per acre is about 1.5-2kg.

2, if the sowing amount is too large, it will lead to too many buckwheat seedlings, stunted growth, which makes the average yield per plant decreased. If the amount of seeding is too small, although the buckwheat seedlings grow under better conditions (nutrients, moisture, light), there will be no competition between seedlings for nutrients, water, but due to the total number of seedlings is not enough, it will lead to a decline in total yield.

Second, buckwheat planting methods

1, land preparation

(1) planting buckwheat plots require a pH of 6-7 or so appropriate, while every 100kg of buckwheat seed production, the need to absorb 3.3kg nitrogen, 1.5kg phosphorus, 4.3kg potassium from the soil.

(2) before sowing, deep plowing and turning about 20cm, and then apply 2000kg of rotted organic fertilizer per mu, 25kg of phosphate, 10kg of potash.

2, sowing

(1) in the middle and late June to early July each year sowing, the amount of seed per acre of land is about 2.5-3kg.

(2) Before sowing, place the seeds in the sun to dry for about 1-2 days, and then soak the seeds with 5-10% grass ash leaching solution.

(3) Strip sowing. Sowing row spacing of 35-50cm, sowing depth of 3-4cm.

3, management

(1) when the buckwheat seedlings grow to 3 true leaves when the inter-seedling fixed seedlings. If it is a higher fertility plots, retain 60,000 seedlings per acre. If it is a lower fertility plot, retain 80,000 seedlings per acre.

(2) At the end of interplanting and seedling setting, the first mid-tillage is carried out, and the second mid-tillage is carried out at the time of early flowering. Before closing the rows, stop mid-tillage.

(3) during the flowering of buckwheat, the use of 0.3% potassium dihydrogen phosphate solution + 0.3% urea solution for foliar spraying (mixing ratio of 3:1), every 7-10 days spraying, a *** spraying 2-3 times.

(4) buckwheat bloom period, in the sunny days during the morning 8-10 o'clock, the use of straightened rope in buckwheat inflorescences above the drag, to promote pollination (every 2 days, a *** for 3 times).

(5) When 75-80% of the buckwheat kernels are ripe, harvesting.
