Problems solved by technology

[0008] As the demand for sorghum as a raw material for wine processing and feed ingredients is increasing, the market demand for sorghum has increased sharply. Moreover, in recent years, droughts and floods have occurred frequently, as well as the reduction of arable land and the increase in population. The production of sorghum has become impossible. Meet the needs of the market

Embodiment Construction

[0028] The following examples further illustrate the present invention:

[0029] 1. Experimental group: the cultivation method of intercropping autumn sorghum after tobacco using the method of the present invention

[0030] A. On June 25, 8 days before planting, spray 0.5 kg of 40% glyphosate water with 50-60 kg of water to spray and weed the whole field;

[0031] B. One day before sowing, soak the sorghum seeds in water at room temperature for 12-24 hours. After soaking, take out the seeds and dress them with a mixture of chlorpheniramine and carbendazim, and then sow immediately;

[0032] C. On July 3, when the tobacco leaves are roasted and there are still 3-5 leaves, the seeds will be sown in the upper middle part of both sides of the tobacco box according to the seeding amount per mu of 0.75-1 kg, and the hole spacing is 35-40 cm. , Sow 5-6 seeds per hole, cover the seeds with fine mud after sowing, and cover the seeds with a thickness of 2-3 cm;

[0033] D. Spraying herbicides to...

Abstract

The invention discloses a high-yield cultivation method for interplanting autumn sorghum after harvesting of tobacco leaves. The method includes the steps of preparation of land for growing field crops, spraying of weed killers for weed extirpation, seed treatment, sowing, spraying of weed killers for extirpating the weeds, extirpating of tobacco stems, dressing of hole applied fertilizer, spraying of chemical for prevention of plant diseases and insect pests, thinning and final singling, dressing of stalk strengthening fertilizer, spraying of chemical for prevention of the plant diseases and insect pests, and timely harvesting. By means of the high-yield cultivation method for interplanting the autumn sorghum after harvesting of the tobacco leaves, the growth season and soil sources idled after tobacco leaf curing is conducted can be fully utilized, harvesting of the tobacco leaves and harvesting of the autumn sorghum are achieved, the tobacco land cropping index is increased, the crop yield per unit area is increased, and economical benefits are increased.

Description

Technical field [0001] The invention belongs to the technical field of crop cultivation, and particularly relates to a high-yield cultivation method for interplanting autumn sorghum after tobacco. Background technique [0002] Sorghum belongs to the Gramineae family, sorghum genus. Also known as shochu and milo, high-yield crops are known as "iron crops" by the masses. They are cultivated widely in China, with the most in Northeast China. Sorghum grains are used for food, winemaking (sorghum wine) or caramel production. The planting of sorghum can be divided into two types: spring cropping and autumn cropping. The sowing period of spring cropping is about mid-to-late March to early April. The time should not be too early. Because the early sowing temperature is low, the growth is slow, and it is easy to die in the cold current. For autumn crops, choose to plant between late June and late July. The time should not be too late to avoid low temperature in the middle and late stage...
