The material component of saline-alkali land soil conditioner and weight part form and prepare variant production by above-described embodiment, extract No. 1, No. 2 and No. 3 three kinds of different saline-alkali land soil conditioners carry out following field test checking according to randomly assigne.
experimental field overview
Test and carry out on cotton breeding base, Xinjiang academy of agricultural sciences, Bao Jiadian town, Manasi, xinjiang county annual April-November.This base is positioned at Tianshan Mountains mountain system North Slope of Middle Section, Southwest Junggar Basin, is in typical desert grey soil area, apart from Manas County 28km, apart from Bao Jiadian town 17km.The continental arid in Shu Zhong temperate zone, test site, semiarid climatic region, steam output is greater than quantity of precipitation, day and night temperature great disparity.Sea level on the average 489 meters, the total effective temperature of >=10 DEG C is 3584 ° of C, average annual sunshine number 2886 hours, frostless season 135-170 days, soil pH 8-9.
test design
Under the measure condition of Optimized water-nitrogen management, saline-alkali land soil conditioner product is filled with water droplet by component design, method for before cotton emerges, modifying agent is put into fertilizer spreading tank water-soluble after carry out dripping and execute.
Experimental field broadcast front base and execute diammonium phosphate 20kg/ mu (16-46-0), test establish do not execute modifying agent contrast ck process, the product 1 by raw material different ratio, product 2, product 3, amount to 4 process, 3 repetitions, the arrangement of random district, community group, experimental plot area 69.2m
2(6.92m × 10m).Topdress in cotton development stage, pouring water adopts the water and fertilizer management technology of optimization, see the following form 2, cultivation management measure is consistent with local land for growing field crops.Each process setting sees the following form 1:
The process of table 1 saline-alkali land soil conditioner:
Table 2 cotton development stage liquid manure scale:
3. sample collection method and mensuration
Using before and after modifying agent and the cotton boll blowing phase measures total salt etc. of each community 0-10cm, 10-20cm, 20-40cm degree of depth soil sample.The method of sampling: every community, with earth boring auger multidraw (continuous sampling of sampling point annex), is mixed into a sample and analyzes.
output of cotton measures
Cotton boll blowing Qi Ge presses community, in, upper each 50, adopt complete blow-of-cottons cotton and weigh, calculate output.
test-results
Table 3 modifying agent process ratio of desalinization and output of cotton
From modifying agent product ratio of desalinization and output of cotton analytical results, see table 3, between 4 process, apply fertilizer, measure of pouring water all makes cotton development stage soil salt reduce; From soil plough horizon 0-40cm ratio of desalinization situation, to use modifying agent product large compared with the process ratio of desalinization not executing modifying agent, desalting effect is remarkable; From output of cotton, output of cotton obvious effect of increasing production after use modifying agent.
conclusion
The modifying agent product that it is main raw material with rare earth silicon-calcium mineral substance, citric acid, polymaleic acid that North SinKiang saline-alkali land soil conditioner is recommended; Using method is: after sowing cotton seed, emerge before, the saline-alkali land soil conditioner of this formula is applied fertilising to fill with, execute with water droplet with droping irrigating pipe, after using modifying agent, effectively can reduce cotton development stage (especially seedling stage) salt content, improve output of cotton.
Shown by above-mentioned experimental study:
1. saline-alkali land soil conditioner provided by the invention is strongly-acid, has and reduces soil pH effect, can execute with droping irrigating pipe with water droplet, and it is simple, convenient to use.Acid has neutralizing effect to alkali, and fertilizer pH is only less than 7, apply alkalescence (this study area pH is 8-9) soil and namely have the effect of reduction soil pH, and this modifying agent pH is 3-5.The feature of water soluble fertilizer is exactly that fertilizer can be dissolved in the water rapidly, and the advantage of drip irrigation is to meet after fertilizer enters fertilizer spreading tank water dissolution, executes enter near crop root with facilities such as droping irrigating pipes with water droplet, this feature is the combination of water soluble fertilizer and drip irrigation advantage.
2. saline-alkali land soil conditioner provided by the invention contains certain organic composition, has the effect improving soil physics structure, increase soil fertility.The main raw material citric acid of this modifying agent, polymaleic acid are organic substance, and namely can improve soil physics structure after being manured into soil, increase soil fertility, this is the characteristic of organic substance, and therefore this effect does not need another attached experimental data explanation.
3. saline-alkali land soil conditioner provided by the invention is used in plant-growth early stage, and desalting effect is remarkable, effectively can reduce the impact of salt damage on plant emergence.This modifying agent contrasts before and after using, and see table 3, soil salt reduces, ratio of desalinization reaches 55-65%, desalting effect highly significant.
