Problems solved by technology

Kenaf is suitable for planting in middle-to-high-grade soil. Since kenaf is a light-loving and warm-loving crop, it is currently mainly planted in Guangdong, Guangxi, Zhejiang, Henan, Shandong, Anhui, Jiangsu, Hunan, Hubei, Jiangxi, Sichuan and other provinces and autonomous regions. Extended to the Northeast Cold Region

Embodiment 1

[0068] Land preparation: Mingshan Farm in Heilongjiang, with a land area of ​​30 mu, land conditions: 35-degree slope land, meadow sandy loam soil, and no soybean harvest in the previous stubble. The organic matter content of the land is 2wt%, and the pH value is 6.2. Plow the ground in the autumn of the previous year, carry out deep plowing, soil preparation, ditching, and ridges with a distance of 65-70cm. Rotary plowing once in spring, harrowing twice to reach the state of sowing.

[0069] Fertilizer preparation: organic fertilizer, urea, water-retaining agent, potassium superphosphate, and potassium chloride are compounded into a compound fertilizer for use, and 70 kg of organic fertilizer (purchased from Shanghai Zhongwei Biochemical Co., Ltd.) per mu, 10 kg of urea, and water-retaining agent 5 kg, 3 kg of potassium superphosphate, and 6 kg of potassium chloride.

[0070] Sowing: Sowing on May 11. Seeder precision on-demand sowing, the sowing rate is 0.5-0.6 kg / mu, two...

Embodiment 2

[0080] Land preparation: Lanxi County, Heilongjiang, with a land area of ​​600 mu, heavily salinized land. The organic matter content of the land is 3.64%, and the pH value is 9.02. In the autumn of the previous year, the land was deeply plowed, prepared, ditched, and ridged, with a ridge distance of 67 cm. On May 11, mechanical rotary tillage, fine trimming, and fine harrowing were carried out.

[0081] Fertilizer preparation: organic fertilizer, urea, water-retaining agent, potassium superphosphate, and potassium chloride are compounded into a compound fertilizer for later use. Apply 75 kg of organic fertilizer (purchased from Shanghai Zhongwei Biochemical Co., Ltd.) per mu, 20 kg of urea, and water-retaining agent 7 kg, 8 kg of potassium superphosphate, and 6 kg of potassium chloride.

[0082] Sowing: Sow on May 15th, sow in drill with a seeder, the sowing rate is 0.5-0.6 kg / mu, two rows on one ridge, the row spacing is about 32cm, the sowing depth is 2-3cm, and the compou...

Embodiment 3

[0092] Land preparation: Lanxi County, Heilongjiang, with a land area of ​​600 mu, heavily salinized land. The organic matter content of the land is 4.04%, and the pH value is 8.11. In the autumn of the previous year, the land was deeply plowed, prepared, ditched, and ridged, with a distance of 67 cm. On May 20, mechanical rotary tillage, fine trimming, and fine harrowing were carried out.

[0093] Fertilizer preparation: organic fertilizer, urea, water-retaining agent, potassium superphosphate, and potassium chloride are compounded into compound fertilizer for use, and 90 kg of organic fertilizer (purchased from Shanghai Zhongwei Biochemical Co., Ltd.), 15 kg of urea, and water-retaining agent are applied per mu 8 kg, 8 kg of potassium superphosphate, and 8 kg of potassium chloride.

[0094] Sowing: Sow on May 21, sow in drill with a seeder, with a sowing rate of 0.5-0.6 kg / mu, two rows on a ridge, with a row spacing of about 35cm, and a sowing depth of 2-3cm. Apply compound...

Abstract

The invention discloses a planting method of kenaf. The planting method comprises the following steps of: (a) performing deep plowing, land preparation, channeling and ridging on planting land in autumn, and performing mechanical rotary tillage, fine land preparation and fine harrowing in spring; (b) sowing in May, applying a composite fertilizer below seeds and isolating with the seeds; (c) performing inter-tillage during growth; and (d) harvesting the kenaf from the middle ten days and the last ten days of September to the first ten days of October. By using the method, the kenaf can be planted in northeast area and even in the desertified land, the useless land is changed into useful land, the planting land cost is reduced, the land quality is improved through continuous planting, high-grade tillable land is provided while ecological deterioration is inhibited, the content of cellulose in phloem of the planted kenaf reaches about 65 percent by weight; and conditions are created for large-scale promotion of cellulosic ethanol.

Description

technical field [0001] The invention relates to a method for large-scale planting of kenaf as an energy crop raw material on desertified land in a cold northeast region and improving the soil, belonging to the fields of bioenergy, agricultural planting and ecological management. Background technique [0002] The mass planting of energy crops is the basic condition for the industrialization and large-scale promotion of biomass energy. The planting of energy crops is not only to solve the global energy crisis, but also must consider the factors of the land crisis. In particular, the development of energy crops in my country faces the problem of unoccupiable arable land due to the decline in the quality and quantity of agricultural land in our country. , can not use food crops and other restrictions. [0003] Among biomass energy, cellulosic ethanol is the most important type, and it is also the type most recognized as the future development direction. However, in the world, t...
