Fertilizing method of tobacco planted in muddy field

Abstract

The invention discloses a fertilizing method of tobacco planted in a muddy field. The land condition of the muddy field is improved by three steps of (1) early stage field treatment, (2) middle stage soil fertilization and (3) later stage soil maintenance, biogas residues are mixed in the land firstly, the biogas residues can adsorb inorganic fertilizers and change the hardness of the soil at the same time, then fertilization is carried out in a trench fertilization manner, the inorganic fertilizers slowly release to ensure the durability of the fertility, finally roots and trunks of tobacco plants are recycled in the land to carry out circulation work, the soil is improved after long-term planting, in this fertilization manner, the fertility is enough, the utilization rate of the fertilizers is high, the growth of the tobacco plants is satisfied, and as the tobacco plants are grown on the muddy field, the economic benefit is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of tobacco planting, in particular to a method for fertilizing tobacco mud and sand field planting. Background technique

[0002] Sediment fields are different from mud fields. Sediment fields are sandy soils. In sandy soils, organic matter content is relatively small, which is an important reason for loose soil structure and easy leakage of water and fertilizer. Therefore, the fertilization of sandy soil should pay special attention to the application of organic fertilizers. Long-term application of organic fertilizers can improve the fertility of sandy soils. Since inorganic fertilizers are easily soluble in water, inorganic fertilizers applied to sandy soils are also likely to be lost with the flow of water. Therefore, solving the loss of water and fertilizers in sandy soils is the key to applying inorganic fertilizers.

[0003] Due to its own characteristics, nitrogen fertilizer is the most easily lost ...

Examples

Embodiment 1

[0025] Embodiment 1, choose a silt field, plant tobacco, adopt the following fertilization methods to fertilize:

[0026] A kind of fertilization method of tobacco silt field planting, its concrete steps are as follows:

[0027] ①Initial land treatment:

[0028] A. Select biogas residues that have normally produced gas for more than two months in the biogas digester, turn them over in the sun, and use limestone to sterilize them to sterilize the bacteria in the biogas residues. After turning them over, evenly disperse them on the upper surface of the sand field;

[0029] B. Use a rotary tiller to plow the land, and the plowing depth is 20 cm. After the plowing is completed, use a land leveling machine to organize the land into a flat land;

[0030] C. Use a fertilizer spreader to sprinkle inorganic fertilizers on the land, and the organic fertilizers use inorganic fertilizers that promote tobacco germination;

[0031] ② Mid-term soil fertilization:

[0032] A. After tobacco...

Embodiment 2

[0042] Embodiment 2, go to a silt field near embodiment 1 to plant tobacco, and the fertilization method adopts the common fertilization method.

[0043] Statistical output year by year, the data is shown in Table 1, and the tobacco quality, the data is shown in Table 2:
