Abstract

The invention belongs to a kind of method in alkaline land soil planting forage grass；The salt-soda soil area feature mainly lacked according to freshwater resources, emphasis, which solves herbage, normally to emerge, survival rate low the problem of lacking with yield after emergence.Pass through the structural analysis to soil and the growth characteristics to pasture crop, pass through engineering means and the Cultivate administration measure for meeting life science, and carry out improved soil and top dressing seedling-protection using special organic fertilizer, thoroughly cast out addition inorganic salts and the improved soil technique with fresh water flush salt so that economical, replicability of the invention and long-term effect.

Description

A kind of method of salt-soda soil planting forage grass

Technical field

The invention belongs to soil improvement and agricultural plantation technology field.

Background technology

Improved constantly with the living standard of the people, the development of animal husbandry constantly expands.At the same time, fodder grass supply and demand lance Shield becomes increasingly conspicuous, particularly high quality grass material critical shortage, and forage feed can not meet existing market demand at all, or even occur Situation with high price from state's outsourcing grass product, the income of peasants and herdsmen's animal husbandry are decreased obviously.Therefore Planting Grass dynamics is increased, The good quality and high output ALFALFA PRODUCTION base based on clover is established, realizes industrialization management, forage grass supply capacity is improved, fills up careless production Product breach, it is extremely urgent, it is very urgent.And by improveing salt-soda soil kind grass and alleviating the pressure of natural meadow, reduce Cultivated land occupancy, have important practical significance.

The whole nation has substantial amounts of saline alkali land resource to need to be developed, but bottleneck due to improving technology and cost and in drought The problem of ground planting forage grass, hinder the development of related industry.Such as emergence rate is low, seedling stage easy dead seedling, long potential difference, do not have Enough yield, the problems such as Grass Quality is not up to standard.So there is an urgent need to a kind of method can improve salt-soda soil in combination with herbage Characteristic, solve existing problem, for China's animal husbandry development and soil improvement provide one it is existing economical and can fit extensively Method.

The content of the invention

The invention discloses a kind of method for improveing heavy salinized ground and the alkaline-resisting crop of plantation.Solves arid with lacking fresh water Area is comprised the following steps due to that can not reduce the problem of salt content causes to plant with fresh water salt discharge：

40-50cm is ploughed deeply into salt-soda soil, and bulk soil is smashed；Every mu with 1 ton of rice husk simultaneously, ploughs deeply to bottom 40cm- 50cm depth.

After biological organic fertilizer made of dead spoil bits will be decomposed with microbial method broadcasts sowing according to every mu of 1000kg Turn over, depth 15-25cm.Bio-organic fertilizer contains withered grass bacterium, lactic acid bacteria, the microorganism species of saccharomycete and actinomyces.

Turned over again once within 20 days after broadcasting sowing organic fertilizer, ploughed depth 20-25cm.

Pour drainage facility：After leveling land, pin type watering appliance is installed.It is required that per 200-300 mu a bite wells（Water Canal）, distribution pump, 20m3 water pot or pond, intake bottom are fixed on apart from tank（Tank）15 centimetres of bottom.

Sowing：Sowed from suitable local clover grass seeds.If alfalfa is according to every mu（667 square metres）1- 1.5 kilograms of sowings.

20 days after emergence, general salt-soda soil planting forage grass class crop easily occurs that leaf is withered and yellow and Large Scale Death.This The organic amino-acid liquid punching fertilisings of Shi Caiyong, 20 kilograms of every mu of dosage is according to 1：After 100 are diluted to holding vessel, entered with watering device Row fertilising.

Apply after amino-acid liquid fertilizer the 5th day, with organic amino-acid liquid fertilizer with 1：Page is sprayed after 500 dilution proportions Face, strengthen herbage leaf photosynthesis, promote root tachyauxesis.

80cm is grown in herbage, is gathered in before blooming, toothing 15cm.After tedding and clearing up field herbage, then enter Amino acid liquid fertilizer punching of row is applied.Dosage is 20 kilograms every mu 1：Irrigated the fields after 100 dilution proportions.

Amino-acid liquid punching fertilising is applied latter 7-10 days, after toothing grows leaf again, with same aminoacids solution Body fertilizer 1：500 dilution sprinkling clover blade faces.

Often gather in later and once repeat [0011] and [0012].

Autumn last time harvesting toothing 10-15cm, does not impose any fertilizer.

Second Year later annual spring, plant sprout before emergence, and in herbage, in the ranks mechanical ditching depth 25cm is simultaneously Applied fertilizer according to every mu of 400kg biological organic fertilizer dosage, then blinding.

When clover grows young leaves, carry out an Amino acid liquid fertilizer punching and apply.Dosage is 20 kilograms every mu 1：100 ratios Irrigated the fields after dilution.

Amino-acid liquid punching fertilising is applied latter 7-10 days, after toothing grows leaf again, with same amino-acid liquid Fertilizer 1：500 dilution sprinkling clover blade faces.

After gathering in herbage, [0011] and [0012] are repeated.

3rd year spring according to（15）Perform.Then repeat（15）-（18）.

Soil can repair completion completely when in the fall, and wherein pH value is down to 7 or so from initial 9-10.Salt content is reduced 50%；Organic matter increases to 1.8-2.5%.Soil texture substantially improves.

Embodiment

The present invention is a kind of method of salt-soda soil planting forage grass, and following instance is the further explanation to the present invention, without It is that a kind of of the present invention is limited.

Example one：

One piece of area, 5 mu of salt-soda soils are randomly selected in township of Changling county of Jilin province the 6th within 2014.Wherein PH9.61, conductance Rate 518us/cm, organic matter 0.89%.

On May 12nd, 2014, carry out ploughing deeply 50cm for the first time, after second time is smashed bulk soil, spread according to 1 ton every mu Ploughed deeply again after broadcasting rice husk.

On May 18th, 2014,1 ton of every mu of the biological organic fertilizer that slag is decomposed containing dead fish is broadcasted sowing, then turns over 20cm.It is raw Organic fertilizer is purchased from Nanyang Zhong Ke Guo Tong Eco Science Technologies Co., Ltd.

Carry out Zhenping on May 20 and pour drainage facility.Because area is small, using drip irrigation equipment.

The alfalfa of Zhaodong No.1 is selected to be sowed as experimental planting according to every mu of sowing 1kg.After planting pour Water is once.

June 10, emergence are all right.

It is downward to there is blade on June 14, crimps.Irrigated the fields after being diluted with water at once using amino acid fertilizer according to 100 times, Every mu uses amino acid fertilizer 20kg.

Alfalfa leaves surface is sprayed after being diluted with water using amino acid fertilizer according to 500 times June 18.It is pale reddish brown after 3 days Clover seedling restore normal growth.

June 25 gathered in once before blooming.The fresh every mu of 1022kg of herbage weight of check weighing.

Drip irrigation herbage after every mu of 20 kilograms of amino-acid liquids fertilizer dilutes 100 times is pressed within 3 days after harvesting immediately.

July 2, herbage toothing grows tall more than 10cm, after every mu of 500 times of 200 milliliters of amino-acid liquids fertilizer dilution, spray Apply blade face.

August gathers in second batch on 10th, average yield per mu alfalfa fresh grass 1030kg.The 3rd day after harvesting, according to（31） Operation is once.

August 18 days, alfalfa leaves surface is sprayed after being diluted with water using amino acid fertilizer according to 500 times.Perform operation （32）.

September is gathered in again on the 30th, and every mu is received 1105 kilograms of fresh grass weight.Toothing 10cm, do not impose with any fertilizer.
