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] From 2011 to 2015, Hengyang Tobacco Company carried out the test and demonstration of the fertilization method of flue-cured tobacco holes in five tobacco-growing counties (cities). The fertilization steps are as follows:

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

[0038] Step 2): then apply 500-600 kg / mu of farmyard manure on the tobacco-specific base fertilizer surface, and the farmyard manure is mainly based on fire soil 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 16-20cm to shovel a trench (length 16-20cm, depth 18-20cm, width 2 ~3cm), one perso...

Embodiment 2

[0044] Compared with Example 1, the difference is that step 1) apply 24 kilograms / mu of tobacco special basal fertilizer in the hole; Step 3): apply 36 kilograms / mu of tobacco special basal fertilizer in strips. (The weight of the tobacco-specific basal fertilizer applied in the hole accounts for 40% of the total weight of the tobacco-specific basal fertilizer.)

[0045] The growth rate of high-quality flue-cured tobacco is 24.56%; the fertilization labor is reduced by 0.8 per mu.

[0046] To sum up, the combined fertilization method of hole application and strip application of flue-cured tobacco provided by the present invention can meet the nutritional requirements of flue-cured tobacco in different growth stages under the fertilization position and fertilization amount, and promote the healthy growth of tobacco leaves to fully mature. , 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 combined fertilization method for holes and strips 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 inappropriate methods of flue-cured tobacco. Some tobacco farmers unilaterally pursue high yield and high output value, and blindly increase the amount of fertilization, which leads to the growth of tobacco leaves that are too large and thick, which is extremely unfavorable for the normal maturity and modulation of tobacco leaves. Field farming is extensive, fertilization is simple, and fertilization is insufficient, and tobacco plants are prone to de-fertilization and premature aging. The second is uneven fertilization. Fertilizer is applied in concentrated holes wi...
