Embodiment 1

[0022] Example 1: The green manure pressing method of mixed sowing green manure in tobacco field, it comprises the following steps

[0023] 1 soaking seeds Before sowing, select the seeds of purple sweet potato and ryegrass and sun-dry them for one day. Before sowing, soak them in warm water at 35°C for 12 hours, then pick them up and dry them.

[0024] the 2 sowing Sow in September, sow or drill, and cover with soil. It is more suitable to sow 1.5kg / mu of ryegrass and purple sweet potato each, and the density of 70,000 plants / mu is more suitable for basic seedlings.

[0025] Fertilizer and water management

[0026] Do a good job in water management to ensure drainage and irrigation. About 15kg of calcium superphosphate and plant ash are mixed together as base fertilizer for each mu, and 10kg of calcium per mu can be applied as top dressing after the seedlings are ready. After spring, apply 15kg of ammonium bicarbonate or ammonium sulfate, and replace the large fer...

Embodiment 2

[0031] Example 2: The green manure pressing method of mixed sowing green manure in tobacco field, it comprises the following steps

[0032] 1 soaking seeds Before sowing, select the seeds of purple sweet potato and ryegrass and sun-dry them for one day. Before sowing, soak them in warm water at 40°C for 8 hours, then pick them up and dry them.

[0033] the 2 sowing Generally, it is advisable to sow in September, and no later than early October. Sow or drill and cover with soil. It is more suitable to sow 2.0kg / mu of ryegrass and purple sweet potato each, and control the density of 100,000 plants / mu for basic seedlings.

[0034] Fertilizer and water management

[0035] Do a good job in water management to ensure drainage and irrigation. About 20kg of calcium superphosphate and plant ash are mixed together as base fertilizer for each mu, and 15kg of calcium per mu can be applied as top dressing after the seedlings are ready. After spring, apply 10kg of ammonium bica...

Embodiment 3

[0040] Example 3: The green manure pressing method of mixed sowing green manure in tobacco field, it comprises the following steps

[0041] 1 soaking seeds Before sowing, select the seeds of purple sweet potato and ryegrass and sun-dry them for one day. Before sowing, soak them in warm water at 38°C for 10 hours, then pick them up and dry them.

[0042] the 2 sowing Generally, it is advisable to sow in September, and no later than early October. Sow or drill and cover with soil. It is more suitable to sow 1.8kg / mu of ryegrass and purple sweet potato each, and the density of 85,000 plants / mu is more suitable for basic seedlings.

[0043] Fertilizer and water management

[0044] Do a good job in water management to ensure drainage and irrigation. About 18kg of calcium superphosphate and plant ash are mixed together as base fertilizer for each mu, and 12.5kg of calcium per mu can be applied as top dressing after the seedlings are ready. After spring, apply 12kg of am...

Abstract

The invention discloses a mixed seeding green manure dressing method for a tobacco field. According to the method in the invention, mixed seeding is carried out on ryegrass and Chinese trumpet creeper in an equal ratio from the first ten days of September to the first ten days of October, wherein the seeding amounts of the ryegrass and Chinese trumpet creeper are 1.5-2.0kg/mu respectively, basic seedling amount is 70000-100000 plants/mu, 1500-2000kg of fresh samples are turned over and buried in per mu of soil with the depth of 10-20cm at the time of 40-45 days before flue-cured tobacco transplanting, and the pure nitrogen applying amount is reduced by 1.8-2.4kg/mu when tobacco seedlings are transplanted. The method comprises soaking seeds, seeding, fertilizer water management, turning over and burying and fertilizer application when the tobacco seedlings are transplanted. By using the method, the problems that when the fertilizer is singly applied for a long term, the carbon-nitrogen ratio in the tobacco field is reduced, nutrient is not balanced, effective fertilizer supplying capacity is weak, and the chemical components of tobacco leaves are inconsonant are solved. The method has the advantages that quick-action nutrient content, total bacterial count and nitrobacteria and actinomycetes quantities in current-season tobacco transplanting soil are obviously increased, the nutrient of the tobacco plants is consonant, the potassium-increasing base-reducing effect of the tobacco leaf is obvious, aroma quality is improved, and the benefit of tobacco planting is greatly improved. The method has good popularization value in the aspect of modifying the long-term continuous cropping tobacco field.

Description

technical field [0001] The invention relates to a green manure pressing method for mixed sowing of tobacco fields, and belongs to the technical field of green manure pressing methods for improving tobacco fields. Background technique [0002] The existing long-term continuous cropping of tobacco planting pays more attention to chemical fertilizers and ignores organic fertilizers, resulting in a decrease in soil carbon-nitrogen ratio, deterioration of physical and chemical properties, and nutrient imbalance, resulting in reduced quality of tobacco leaves and low tobacco planting benefits. In order to solve the above problems, green manure is currently used to improve the physical and chemical properties of tobacco planting soil and improve the soil's effective fertilizer supply capacity. Therefore, it is imperative to rationally rotate crops and replant green manure, improve the soil for tobacco planting, and achieve the combination of land use and land cultivation. Due to t...
