Sustained high temperatures and droughts have caused and are causing damage to agricultural production this year and cannot be underestimated. There are also many ways to fight against natural disasters. Among them, planting buckwheat can give full play to the effects of short, flat, and fast.
Buckwheat is a green food with unique flavor and natural pollution. It also has good medicinal value. Buckwheat has a short growth period and quick effect. It takes only 70--80 days from emergence to harvest. The yield per mu is about 100 kilograms, and it is suitable for planting on hills, hills, plains, and lakesides. It can fill up the affected areas. The blank can also increase the income of farmers.
In order to increase the yield of buckwheat, the following points should be mastered in cultivation techniques:
Use good quality varieties. The varieties with excellent traits include Taixing buckwheat, Jiujiang bitter buckwheat, Pingyu No.2, Fujian, Japan Xinzhou tetraploid buckwheat and Limao, etc., which can be selected according to local conditions. However, it is forbidden to use stored for many years. Because the germination rate of the seed is very low, only the seeds harvested in the previous year can be used. When the selected seeds were examined carefully, the endothelium of the germinating seeds was green, and the seeds that did not germinate or had a low germination rate showed yellow endothelium.
Fine soil preparation and fertilization. After the harvest, it is necessary to rush to pick it up in time. As the buckwheat top is weak, it is necessary to make the earth bubble grass and make it empty. To apply fertilization on the ground, apply 2000--3000 kg of ash compost per mu and apply 15-20 kg of phosphate fertilizer. To achieve a deep ditch lift, easy irrigation and drainage. Car width to 2 meters is appropriate.
Ding Dingmiao appropriate period. The sowing date begins in early August and ends in late. The sowing rate per acre is 4--5 kg. Sowing planters can be used for spreading, hole sowing, and sowing, but it is advocated mainly for drilling. Ditch deep 3--4 cm, spacing 35 cm. When the seedlings are 5-8 cm tall, they combine tillage and weeding. Basic seedlings per acre 10-150 thousand.
Timely fertilizer to raise seedlings. In order to cultivate strong seedlings and increase grain weight, when the buckwheat seedlings are up to 10 cm or more, 5 kg to 6 kg of urea should be collected per acre. After entering the flowering and fruiting period, 0.5% urea and 0.2%-0.3% potassium dihydrogen phosphate solution should be mixed to conduct extra-root fertilizer application, or to spray 500-600 times Huimanfeng active liquid fertilizer.
Artificially assisted pollination. Since buckwheat has low self-initiative capacity, the natural pollination rate is only 20% - 30%. Therefore, after entering the flowering stage, bamboo culms about 3 meters long should be used to bring buckwheat plants to the sunny or cloudy days from 9 to 10 o'clock in the morning. Back to incitement, help pollination, instigated once every 5 days, can increase the seed-setting rate of about 40%.
Timely early harvest. As the grains of buckwheat are mature in stages and fall off easily, generally after 70% of the grains become dark, they are harvested when the dew is dried in the morning. Harvest time is from late October to early November.
