Sorghum wine-making mellow taste good wine-making sorghum high-yield planting techniques

I. selection of sites

Sorghum was planted in loam or sandy loam with fertile soil, deep soil layer, uniform soil fertility, flat terrain, convenient irrigation and drainage, away from pollution, slightly acidic to weakly alkaline loam, so as to lay a good foundation for high and stable yield.

2. Seed selection and sowing

It is necessary to select fine varieties of wine-making sorghum which have been approved by the state (or provincial or municipal level) and are suitable for local cultivation, which have the characteristics of high quality, high yield and multi-resistance. Excellent seeds with full and neat grains, no injury or disease, purity ≥ 99%, purity ≥ 97%, germination rate ≥ 95%, water content ≤ 13% should be selected and dried in the sun for 2 to 3 days to improve their germination energy and germination rate. When the inland temperature of 8 cm plough layer is 12 ℃ and the soil water content is about 18% for 5 consecutive days, the seeds can be sown. The best sowing date is the middle of June, and the mechanical strip sowing on the ridge should be carried out, the sowing amount per mu is 0.5-0.8 kg, the sowing depth is the same, and the suitable thickness of covering soil after suppression is 2 cm.

3. Weeding

The combination of chemical weeding and artificial weeding was carried out to remove all kinds of weeds. Chemical herbicides suitable for use before sowing, before or after emergence of sorghum and have no toxic effect on the next crop can be selected. The artificial weeding should be completed three times after the seedling and before the ridge closure, and the large weeds in the field and around should be uprooted or pulled out in the later growth stage, so as to reduce the occurrence number and harm degree of weeds in the following year.

IV. Fertilization

The cultivation of wine sorghum adheres to the principles of formula fertilization, balanced fertilization, stage fertilization, on-demand fertilization, the combination of agricultural fertilizer, chemical fertilizer and micro-fertilizer, and the combination of base fertilizer, seed fertilizer and topdressing fertilizer. The specific times, periods, types, quantities and methods of fertilization should be flexibly mastered according to seedlings, time, days, and local conditions. Usually, each mu should apply fully mature high-quality farm fertilizer 4000kg / mu, ternary compound fertilizer (15-15-15) 15kg / mu and appropriate amount of zinc, iron, selenium and other micro-fertilizers as base fertilizer, and use 8kg diammonium phosphate as seed fertilizer (seed is above, fertilizer is under, seed and fertilizer should be 6-8cm apart), and urea 20kg / 25kg as panicle-attacking fertilizer before jointing stage.

V. Prevention and control of diseases and insect pests

The cultivation of wine-making sorghum should carry out the plant protection policy of "prevention first, comprehensive control", and achieve early prevention, early detection and early control. During the growth period, pollution-free pesticides or biological pesticides with broad spectrum, high efficiency, low toxicity, low residue and safety to human and livestock must be selected to control leaf spot, smut, armyworm, aphid, borer and other diseases and insect pests in time. The same agent should not be used more than twice in a row to avoid drug resistance. All kinds of diseases should be controlled at the initial stage of sorghum disease or before the disease spreads, and all kinds of pests should be controlled during their spawning period or larval incubation period, which can not only get twice the result with half the effort, but also reduce the number of drugs used, prevent environmental pollution, realize energy saving and environmental protection, and reduce production costs.
