Planting techniques and matters needing attention on how to plant sugarcane

Sugarcane is a common fruit in daily life. Because of its good taste and high edible value, there are a large number of people who like to eat it. Now the market sales of sugarcane is very high, so it attracts a lot of people to plant. However, before planting, we should still have a more comprehensive understanding of its planting technology.

How to grow sugarcane

1. Variety selection: excellent varieties with high yield, high quality, disease resistance, good adaptability and good taste should be selected. Sugarcane shoots with thick, uniform, crack-free, broad green leaves, disease-free and insect-free shoots should be selected.

2. Seed soaking: selecting full, pest-free and injury-free twin-bud seedlings and soaking seeds with clear water or 2% lime water for 2 days can improve the drought resistance of sugarcane seeds and achieve the effect of eliminating diseases and insect pests.

3. Reasonable close planting: there are 6 sugarcane varieties per 100 cm planting ditch and 3000ml sugarcane varieties per mu. The planting density is generally controlled at about 20 buds per 100 cm, ensuring 4500mur5500 effective stems per mu.

4. Wide row: the row spacing of sugarcane planting should be 90ml 100cm, which is beneficial to ventilation and field management after planting.

5. Shallow species: the depth of sugarcane returning to soil cover is generally about 5 cm.

6. the following method: double-row-to-air planting is adopted, and the sugarcane seeds should be placed flat in the planting ditch with the buds facing both sides. when returning to the soil to cover the seeds, the seedlings should be gently pressed into the soil, and then covered and compacted to facilitate rooting.

Sugarcane planting techniques and matters needing attention

1. Planting time:

1. Land selection and machine ploughing: sugarcane planting should choose convenient drainage, deep, loose and fertile soil conditions to fully meet the needs of its root growth, so as to make the root system play a better role in absorbing water and nutrients. If the previous crop is sugarcane, you should first use a rotary tiller to break the sugarcane head, so that not only the pieces of soil can be broken up, but also the harm caused by sugarcane sawing longicorn beetles can be reduced; the cultivated land should be ploughed with a high-horsepower tractor, preferably 35-40 cm deep and 20-25 cm wide at the bottom of the ditch, and the soil after ploughing should be fine and flat.

2. row spacing and opening: if the land with good water and fertilizer conditions, the row spacing can be appropriately increased, the row spacing should be 1 m to 1.2 m; if it is sloping land, small row spacing should be selected, 0.8 m to 1 m should be planted. The slope should run parallel to the contour line, and the direction should not go down the slope, otherwise the rain will wash out the fertilizer and sugarcane seeds.

3. Reasonable close planting: the sugarcane seeds should be placed flat in the planting ditch, the buds on both sides, and the seedlings should be gently pressed in when returning to the soil to cover the seeds. After the soil, return to the soil to cover and compaction, in order to facilitate the root. There are 6 sugarcane seeds per 100 cm planting ditch, and the sugarcane seeds should be placed flat in the planting ditch with buds facing both sides. When returning to the soil to cover the seeds, the seedlings should be gently pressed into the soil, and then covered and compacted to facilitate rooting. The row spacing of sugarcane planting is required to be 90ml 100cm, and the depth of sugarcane seed returning to soil cover is generally about 5cm. The planting density is generally controlled at about 20 buds per 100 cm, ensuring 4500mur5500 effective stems per mu.

2. points for attention:

The planting time of fruit sugarcane is from September of that year to February of the following year, and there is no sugarcane seed too early, which affects the yield and quality too late.

How to fertilize sugarcane

1. Fertilizer for raising seedlings: after emergence, combined with weeding for the first time, 15kg urea per mu.

2. Fertilization during the growth period: in the field, 100 kg of superphosphate (or calcium magnesium phosphorus) and 10 kg of nitrogen, phosphorus and potassium compound fertilizer (or potassium chloride) were applied each time during the field growth period.

3. Apply foliar fertilizer and balance fertilizer at the right time. During the growing period, according to the seedling condition, the compound, efficient, pluralistic, organic ecological foliar fertilizer "Rong Dafeng" 300 times liquid was sprayed for 3 times for 4 times. After setting the seedlings, 5% ammonium carbonate water was frequently poured on the roots of the weak seedlings.

Common insect pests in sugarcane and their control

Sugarcane pests are mainly sugarcane borer, followed by pink scale, woolly aphid and sugarcane turtle. The prevention and control methods are as follows:

1. Agricultural prevention and control: mainly adopt fitness cultivation, reasonable close planting, scientific management and fertilization. Select sugarcane shoots with large, uniform, crack-free and wormhole-free shoots as seeds. The distance of planting ditch is 120 cm, the depth of ditch is more than 40 cm, the width of ditch bottom is 20 cm, and 20 buds are sown per meter. Ensure that the effective stem per mu is not less than 4500. During the growing period, the withered seedlings were removed in time, the withered shoots were burned, and the larvae in the stem were killed with injection or needle.

2. Physical control: make use of the phototaxis of adults and install frequency vibrating insecticidal lamps to trap and kill adults.

3. Chemical control: grasp the peak period of occurrence (March-April, June-July, September-October) and dynamic occurrence for control.

Sugarcane needs to do a good job in seed selection before planting, then land selection and soil preparation, and timely application of basic fertilizer during soil preparation. After planting, we need to strengthen management, and the amount of fertilizer applied in different periods is also different, so we should pay more attention to it. Sugarcane is also vulnerable to insect pests, so pest control is also a very important step.
