Description

The fertilizing method of a kind of sugarcane

Technical field

The invention belongs to chemical fertilizer field, be specifically related to the fertilizing method of a kind of sugarcane.

Technical background

Sugarcane is the general name of saccharum, and the modal edible sugarcane of China is bamboo cane.Sugarcane is applicable to planting in fertile soil, the place that sunny, summer in the winter temperature difference is large.Sugarcane is temperate zone and tropical farm crop, is the raw material manufacturing sucrose, and can refines ethanol as energy substitution product.Sugarcane is a kind of important cash crop, applies fertilizer very important in cane planting process, and the size of sugarcane and the height of sugar degree have much relations with fertilising, and the output also affecting sugarcane opportunity of the kind of applying fertilizer and fertilising and sugar degree.

Summary of the invention

The object of this invention is to provide a kind of Sugarcane Fertilization method, by the adjustment of sugarcane fertilizer, the time of applying fertilizer and fertilization type are adjusted, improves the output of sugarcane.

The present invention is achieved through the following technical solutions:

A fertilizing method for sugarcane, is characterized in that, comprises the following steps:

(1) before cane planting, applying fertilizer A is as base manure, base manure is composed of the following components by weight: the brid guano 50-65 part become thoroughly decomposed, silkworm excrement 30-50 part, potassium sulfate 8-12 part, ammonium molybdate 1-2 part, EM bacterium 0.1-0.2 part, every mu of amount of application 1000-1200kg, base manure is evenly sprinkled into before digging, and makes base manure and mixing with soil; After fertilizer and mixing with soil, apply in plantation ditch, earthing is sowed.Fertilizer can not directly contact with kind stem, with unburned bud.

(2) seed manure is attacked, when sugarcane grows three true leaves, in conjunction with soil dressing, impose fertilizer B, fertilizer B is composed of the following components by weight: potassium sulfate 7-9 part, phosphoric acid diamines 5-8 part, 5 parts, urea, plant ash 10-15 part, every mu of applying fertilizer B 100-150kg.Short seedling strong sprout, guarantee full stand.

(3) fetilizer for tillering is attacked when sugarcane grows 6 true leaves, in conjunction with in earth up, impose fertilizer C, fertilizer C is composed of the following components by weight: potassium sulfate 8-12 part, phosphoric acid diamines 5-8 part, plant ash 10-15 part, Asian puccoon 0.2-0.5 part, every mu of applying fertilizer C 130-180kg.Promotion is tillered, and ensures productive tiller quantity.

(4) stem is attacked fertile in Early period of cane elongation, in conjunction with large ridging, impose fertilizer D, fertilizer D is composed of the following components by weight: instant Si-K fertilizer 4-7 part, monocalcium phosphate 5-8 part, magnesium sulfate 1-2 part, borax 0.5-1 part, zinc sulfate 0.2-0.5 part, every mu of applying fertilizer D 100-150kg.Promote that sugarcane sends out root, leaf of growing up, stem of growing up large, guarantee good quality and high output.

The instant Si-K fertilizer that the present invention uses can use the instant Si-K fertilizer on market, and instant Si-K fertilizer easily absorbs, and containing silicon, promotes sugarcane production, can also promote sugar on sugarcane.

Fertilizer of the present invention is made up of fertilizer A, fertilizer B, fertilizer C, fertilizer D, fertilizer A take farm manure as main component, add the potash fertilizer raw material needed for sugarcane production, use EM bacterial classification to improve soil simultaneously, increase soil fertility, improve the utilization ratio of fertilizer, fertilizer A uses before cane planting as base manure; Based on fertilizer and potash fertilizer in fertilizer B, fertilizer C, add Asian puccoon and can promote that sugarcane is to the absorption of fertilizer, using in Sugarcane Seedlings phase, tillering phase, is the nutriment that sugarcane provides nitrogen and potash fertilizer etc. to need, and improves sugarcane production speed; Fertilizer D mainly comprises phosphate fertilizer, potash fertilizer and trace element, uses in sugarcane elongating stage, promote synthesis and the accumulation of sucrose part, make sugarcane yield, sugar degree significantly promotes, and fertilizer specific absorption is high.

Beneficial effect of the present invention: Sugarcane Fertilization method provided by the invention is divided into multiple according to the difference of sugarcane production phase, required for sugarcane different growing stages, the difference of fertilizer is applied fertilizer, scientific and reasonable utilizes fertilizer, not only fertilizer can be economized on, and the sugarcane yield of planting out is high, water content and sugar degree also significantly increase, the mode of simultaneously being arranged in pairs or groups by fertilizer and inorganic fertilizer is applied fertilizer, improve fertilizer efficiency, also the problem of planting the salting of soil caused is avoided, the sugarcane grown is comparatively straight, even thickness.

Embodiment

(1) before cane planting, applying fertilizer A is as base manure, fertilizer A is obtained by weight ratio by following component: the brid guano become thoroughly decomposed 58 parts, silkworm excrement 42 parts, potassium sulfate 10 parts, ammonium molybdate 1 part, EM bacterium 0.15 part, every mu of amount of application 1200kg, base manure is evenly sprinkled into before digging, and makes base manure and mixing with soil; After fertilizer and mixing with soil, apply in plantation ditch, earthing is sowed.

(2) seed manure is attacked, when sugarcane grows three true leaves, in conjunction with soil dressing, impose fertilizer B, fertilizer B is obtained by weight ratio by following component: potassium sulfate 9 parts, phosphoric acid diamines 6 parts, plant ash 12 parts, 5 parts, urea, plant ash 12 parts, every mu applying fertilizer B 125kg.

(3) fetilizer for tillering is attacked when sugarcane grows 6 true leaves, in conjunction with in earth up, impose fertilizer C, fertilizer C is obtained by weight ratio by following component: potassium sulphate fertilizer 10 parts, monocalcium phosphate 6.5 parts, plant ash 12 parts, Asian puccoon 0.5 part, every mu applying fertilizer C 150kg.

(4) stem is attacked fertile in Early period of cane elongation, in conjunction with large ridging, impose fertilizer D, fertilizer D is composed of the following components by weight: instant Si-K fertilizer 5 parts, monocalcium phosphate 6.5 parts, 1.2 parts, magnesium sulfate, borax 0.8 part, 0.3 part, zinc sulfate, every mu of applying fertilizer D 125kg

Sugarcane fertilizer of the present invention is tested 200 mu of sugarcanes, and as experimental group, other 200 mu of sugarcanes are tested as a comparison, are comparative group, and applying fertilizer A is as base manure before planting for experimental group, and every mu of usage quantity 1200kg, uses before planting; Fertilizer B used in tillering phase, every mu of usage quantity 125kg; Fertilizer C used in tillering phase, every mu of usage quantity 150kg; Fertilizer D used in elongating stage, and every mu of usage quantity is 125kg; Comparative group before planting applications of farmyard manure and composite fertilizer by weight the mixed fertilizer 800kg of 15:1; Tillering phase and elongating stage respectively use composite fertilizer 150kg and 120kg, other conditions are identical, display after harvesting, experimental group per mu yield reaches 2.8t, comparative group per mu yield 2.1t, the average sugar degree of experimental group sugarcane reaches 21.3%, comparative group sugar degree 17.5%, as can be seen here, uses the sugarcane yield of fertilizer of the present invention significantly to promote, and the sugar degree of sugarcane significantly promotes, fertilizing method fertilizer cost provided by the invention also declines relative to control group.

The fertilizer specific absorption that the present invention uses is higher, use this fertilizer and plant 5 years continuously, the output of sugarcane can not decline, and the output year after year using composite fertilizer sugarcane when the later stage uses identical fertilizer obviously declines, illustrate that this application process can improve soil, soil fertility can not be caused to decline.
