Planting techniques of Sweet Sorghum

Sugar sorghum, commonly known as sweet stalk, is an edible plant that tastes sweet and juicy. Many rural friends should often eat it when they are young, similar to sugar cane. So do you know how it is planted? Let's get to know it with the editor.

1. Sowing and raising seedlings

Sweet sorghum likes warmth and has the characteristics of drought resistance, waterlogging resistance, saline-alkali tolerance and so on. It can be planted in most parts of the world. It is not strict for the growth environment and has strong adaptability to the soil. So planting is no need to choose what plot to plant, soak the seeds in clean water for one day before sowing, fish them out to dry, can improve the seed germination rate. Its germination rate is low, generally sowing about 1.5 kg per mu, the rhizome is short, and the top soil capacity is weak, so the sowing depth is 2-3 cm. 2-3 leaf time seedlings, 4-6 leaves fixed seedlings, combined with fixed seedlings to remove tillers, to promote a strong seedling, in addition, its tillering ability is strong, if it is not removed early, the main stem and tillers will grow, consume too much nutrients, not only prolong the growth period of the main stem, but also cause the main stem soft, late ripening and other adverse consequences, so it is necessary to remove the tillers in time.

2. Cultivate the soil by ploughing.

The seedlings were ploughed for the first time at 2-3 leaves, which could eliminate weeds, prevent drought and preserve soil moisture;-6 leaves combined with fixed seedlings for the second intertillage, the depth was about 10 cm; the third intertillage was watered 10-15 days after the second intertillage. When the plant grows to about 70 cm, the soil can be closed to cultivate the soil between the rows on the root base of sweet sorghum to promote the growth of pillar roots.

3. Fertilizer and water management

Adequate basal fertilizer should be applied before planting, and appropriate amount of topdressing should be applied during the growing period to facilitate sugar accumulation. Excessive application of nitrogen fertilizer should not be applied in the middle and later stages of sweet sorghum growth, so as to avoid greedy green late ripening and affect sugar accumulation. In the jointing stage of the plant combined with the third ploughing to top fertilizer, 10-15 kg urea per mu, fertilizer should not be applied on the soil surface. The water demand of sweet sorghum is less at both ends and more in the middle. Generally, it needs to be watered 3-4 times during the whole growth period, the first time is in the jointing stage, combined with topdressing, the second time is half a month after the first watering, ah, the flowering stage of poplar is carried out, and the third time is generally carried out in the filling period. in the later stage, we should pay attention to avoid low temperature in time, pay attention to weather changes, so as to avoid lodging.

4. Pest control

The disease resistance of sweet sorghum is strong, and there is generally no disease in the planting process, but the insect resistance is weak, and according to the high sugar content, it is extremely vulnerable to the harm of drill insects and aphids, so it is necessary to control it as soon as possible. Aphids can be sprayed with deltamethrin, but attention should be paid to the concentration of the agent to avoid drug damage. Heart worms can spread several grains of carbofuran in the heart leaves.
