Problems solved by technology

[0006] In order to solve the problems of low fertilizer utilization rate, low yield and low quality of tobacco leaves in the existing fertilization methods, the present invention provides a joint fertilization method for flue-cured tobacco base fertilizer (also known as the method of fertilization by hole and strip), aiming at Improve the utilization rate of fertilizer, reduce the manpower for fertilization, promote the normal growth of tobacco plants, increase the yield and quality of tobacco leaves, and then improve economic benefits

Embodiment 1

[0036] Hengyang Tobacco Company carried out experiments and demonstrations of flue-cured tobacco hole strip fertilization in five tobacco-growing counties (cities) from 2011 to 2015. The fertilization steps are as follows:

[0037] Step 1): Ridge the tobacco field according to 110-120cm, and make holes in the center of the lined smoke ridge at intervals of 45-50cm (the center of the hole) (the hole is applied), and the depth of the hole is 18-20cm. The diameter of the hole is 20-22cm, and 18 kg / mu of tobacco-specific base fertilizer is applied to the hole.

[0038] Step 2): Then apply 500-600 kg / mu of farmyard manure on the special base fertilizer surface for tobacco. The farmyard manure is mainly fire ash and decomposed pig manure.

[0039]Step 3): After applying the hole fertilizer, one person stands on one side of the ridge body and uses a hoe or rake with a width of 16-20 cm to shovel the furrows (16-20 cm long, 18-20 cm deep, and 2 cm wide) between the two holes. ~3cm), ...

Embodiment 2

[0044] Compared with Example 1, the difference is that step 1) applies 24 kg / mu of tobacco-specific base fertilizer in holes; step 3): applies 36 kg / mu of tobacco-specific base fertilizer in strips. (the tobacco-specific basal fertilizer weight of hole application accounts for 40% of total tobacco-specific basal fertilizer weight.)

[0045] The growth rate of flue-cured tobacco top grade tobacco is 24.56%; each mu reduces the manpower for fertilization by 0.8.

[0046] Based on the above analysis, the joint fertilization method of hole fertilization and bar fertilization provided by the present invention can meet the nutritional requirements of flue-cured tobacco at different growth stages under the fertilization position and fertilization amount, and promote the full maturity of tobacco leaves in healthy growth of tobacco plants. , to achieve the purpose of high quality and high yield.

Abstract

The invention discloses a cave and strip combined fertilizing method used for a flue-cured tobacco base fertilizer. Cave fertilizing holes are arranged along a radial direction on a tobacco ridge after a tobacco land is ridged; then stripe fertilizing furrows are arranged among adjacent cave fertilizing holes; tobacco dedicated basal fertilizer is applied in the cave fertilizing holes and the strip fertilizing furrows, wherein the total weight of the tobacco dedicated basal fertilizer in the cave fertilizing holes accounts for 30-40% of that of the tobacco dedicated basal fertilizer; farmyard manure is applied in the cave fertilizing holes before the tobacco dedicated basal fertilizer is applied; the total weight of the strip fertilizer accounts for 60-70% of that of the tobacco dedicated basal fertilizer, and finally the strip fertilizing furrows after being applied with the fertilizer are wrapped with soil. Through the arrangement of cave fertilizing holes and strip fertilizing furrows and match of the fertilizing amount of cave fertilizing and strip fertilizing, the cave and strip combined fertilizing method used for the flue-cured tobacco base fertilizer has the advantages that utilization rate of fertilizer is effectively improved, fertilizing labor is reduced, normal growth of tobacco plants is boosted, tobacco leaf yield quality is improved, thus economic benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and in particular relates to a hole-strip combined fertilization method for flue-cured tobacco base fertilizer. Background technique [0002] In recent years, although the fertilization level of flue-cured tobacco has been greatly improved, there are still problems of unbalanced fertilization level and improper methods, mainly manifested in: First, the unbalanced fertilization amount. Some tobacco farmers one-sidedly pursue high yield and high output value, and blindly increase the amount of fertilization, resulting in excessive growth and thick tobacco leaves, which is not conducive to the normal maturation and conditioning of tobacco leaves. Field cultivation is extensive, fertilization is simple, and if fertilization is insufficient, tobacco plants are prone to defertilization and premature aging. The second is uneven fertilization. If the fertilizer is concentrated in ho...
