After improvement, the salt content of soil layers having depth of 0-30 cm is reduced to 0.15-0.2%, the soil pH value is reduced to 7.2-7.3, the soil humus content is increased by 60-65%, and the total nitrogen content of the soil is increased by 58-59%.

Description

A kind of saltings is with containing the fertilizer of plant modifying agent and the application in Chinese small iris plantation thereof

Technical field

The invention provides a kind of fertilizer and the application in Chinese small iris plantation thereof, be specifically related to a kind of saltings with containing the fertilizer of plant modifying agent and the application in Chinese small iris plantation thereof, belong to technical field of soil fertilizer.

Background technology

There is large-area saltings in China, a lot of saltings due to salt, basicity high, cannot effective planting plants; In the work in artificial reconstructed saltings, most way adopting the consumption wealth effort such as backfilling new soil.

Soil moved in improve the original is exactly soil removal and replacement, and soil moved in improve the original can improve the physical properties in saltings; Have and press down salt, pouring salt, pressure alkali and reinforcement; The effect of soil fertility, can make soil salt content be reduced to the degree of unlikely damage to crops growth; These ways, to the improvement DeGrain of soil, can only be alleviated in short-term, and the time one is long, and soil is salinization once again.

Also have a kind of way in addition, namely adopt chemical improvement agent improvement soil; Use specific fertilizer, improve soil by plantation saline alkali tolerant plant; This method can improve soil preferably, but the dedicated fertilizer that the preparation of this method needs is special, this is the direction being worth further investigation.

Heavy saline 0-30cm soil layer saltiness is high, soil depletion, nutritive ingredient famine; The fertilizer of the current alkaline land improving for heavy saline has following defect: while 1, can not improving soil pH, saltiness, improve soil nutrient structure; 2, the DeGrain of Soil Humus content, content of microorganisms, total nitrogen content is improved; 3, adopt existing fertilizer planting plants in saltings, plant quality is poor.

Summary of the invention

The present invention is the deficiency solving prior art existence, provides the fertilizer of a kind of saltings containing plant modifying agent, to realize following goal of the invention:

The fertilizer application in Chinese small iris plantation of embodiment 5 one kinds of saltingss containing plant modifying agent

Concrete steps are as follows:

1, the selection in saltings

The planting area selected is heavy saline, and 0-30cm soil layer saltiness is 0.58-0.6%, pH is 8.0-9.0, soil depletion, nutritive ingredient famine; Chinese small iris cannot normal growth under these growing area natural condition.

2, vernalization

Vernalization is undertaken greenly by one of committed step of planting by chinensis seed sexual propagation; Carry out vernalization to the wild chinensis seed gathered through 18.4mol/L concentrated sulfuric acid solution immersion treatment, can abolish seed strong, improve percentage of germination and seedling rate, its percentage of germination on average improves 40-50%.

3, nursery

Set up seedling bed, smooth good seedling bed tiles the mixed-matrix prepared, and described matrix is mixed in 2:1 ratio with fine sand by farmland fine earth, and through disinfecting, water content is 30-35%.

Nursery is carried out sowing seeds in seedbed, and seed is the seed after step 2 vernalization process, and every seed spacing 10cm, covers one deck fine earth after having spread seed; When soil is half-dried, feedwater of spraying in time, ensures that soil is moist.

4, apply fertilizer

A kind of saltings of embodiment 1-3 is evenly sprinkling upon with the fertilizer containing plant modifying agent the growing area chosen, every mu of fertilising 200kg, turns over spreading fertile growing area, rake.

5, plant

March plants, and selects the Chinese small iris seedling of high-quality health, the plant deinsectization liquid medicine that spray painting is diluted.

Ditched furrow, every furrow are wide 1.8 meters, and opens a wide 20cm, the irrigation ditch of dark 20cm in the middle of furrow, open wide 40cm between two furrow, the waterways of dark 30cm, every furrow can plant 4 row Chinese small iris seedlings, and spacing is about 40cm.

After planting well, soil blank between furrow is sprayed weedicide, to reduce the impact that Weeds at seedling grows Chinese small iris.

6, irrigate

Make a call to four well casing combination wells in 20 ~ 30m depths, saline-alkali soil district, namely four go out the shared water outlet of hydrophthalmia; Water salinity is 1 ~ 2g/l, and pH value is 7.7 ~ 7.8, and sodium adsorption ratio is 2.3 ~ 2.5.

After plantation, drip washing once, and leaching requirement is 40 ~ 65mm; Once, leaching requirement is 40 ~ 65mm in growth drip washing in mid-term; Once, in lessivation, adopt pipeline or anti-seepage channel water delivery, furrow is irrigated, and also can adopt sprinkling irrigation or drip irrigation in every two weeks drip washing afterwards; Slightly salty is the underground water of shallow-layer 20-30m, and large-area Demonstration And Extension is conducive to controlling phreatic table, prevents the accumulation of salt in the surface soil again.

7, manage

Late April begins to spend, and mid-May, mid-June is flower eventually, and early November is withered and yellow, and the green phase reaches more than 290d to entering full-bloom stage by the end of May; Chinese small iris color and luster is dark green, and spend simple and elegant beauty, nectar delicate fragrance, the florescence reaches more than 55 days.

Will carry out the prevention and control of plant diseases, pest control except weeding a garden, spray 1:2:200 Bordeaux mixture, 70% thiophanate methyl, 1000 times of liquid etc., prevent and treat multiple disease and pest.

8, gather

Flower of Chinese Small Iris: Post flowering is selected fine day and plucked, and dries in the shade or dries;

Semen Iridis: during fruit maturation in 8 ~ September, cut off fruit ear, dry, beat and get seed, removing impurity;

Root of Chinese Small Iris, leaf: 8 ~ September gathers, dry.

The fertilizer adopting the formula of embodiment 1,2,3 to prepare, by the implantation methods of embodiment 5, tests respectively, and the effect specific targets of soil improvement are in table 1, and the experimental result specific targets of plantation Chinese small iris are in table 2.

The effect table of table 1 soil improvement

The experimental result table of Chinese small iris planted by table 2 kind

Through test, implement 2 every soil root system improved effects best, the indices of plantation Chinese small iris is also optimum, is preferred embodiment.
