Description
Technical field
The present invention relates to corn planting technical field, especially a kind of cultural method of rich calcium iron corn.
Background technique
Calcium, iron are the essential microelements of human body, and being must in the daily diet nutritional tension metrics of Chinese Soclety of Nutrition
Standby nutrient.The mineral elements such as calcium, iron can enhance human immunity, is anti-oxidant, the synthesis of regulatory protein matter etc. has
Important function.Iron deficiency will cause anaemia, and body immunity, locomitivity and intellectual development etc. are affected.
Corn is to be distributed one of widest cereal crops in the world, and cultivated area is only second to wheat and rice and occupies third
Position；Plantation distributed areas in China are vast, and gross annual output amount is big, and the yield of China's conventional corn in 2013 is up to 215,000,000 tons
First generalized grain crop.In solving approach of the mankind to microelement demand, the bioaugmentation measure of corn microelement is
One of most important approach.
During conventional corn plantation, mineral element is increased by the fertilizer that rationally assembles and plan strategies for farming measure
The accumulation of calcium, iron in seed is a kind of sustainable, safe and economic scheme to improve corn calcium, iron content.
At present there are mainly three types of the methods of domestic production selenium-rich zinc-iron nutrient corn: first is that in foliage-spray solution fertilizer,
But leaves of plants is not main absorption of nutrient ingredients organ, absorbability is limited, it is easy to trickle down to field, to field runoff
Water and soil cause certain pollution.Second is that root apply, but mineral ions be easy solidification, utilization rate is low, pedo relict compared with
Greatly.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of cultivation side of rich calcium iron corn
Method.
It is achieved particular by following technical scheme:
A kind of cultural method of richness calcium iron corn, including site preparation, sowing, field management and harvesting step, which is characterized in that
Specifically includes the following steps:
(1) site preparation: selecting loam to deep plough as planting site, and to it, before corn plantation, using calcium it is iron-based it is fertile into
Row improvement soil；
(2) it sows: corn seed being seeded on reclaimed soil, and is mixed with activation bacterial manure on the periphery of corn seed
Soil；
(3) field management: including pouring water and using rich calcium iron flake leaven, later period spraying worm medicine in the corn jointing stage；
(4) harvest: after corn ear wire vent, the silk at top becomes brown, and harvesting when having sagging.
The production method of the iron-based fertilizer of step (1) calcium are as follows: in terms of quality point, by 10-20 parts of shells, 15-35 parts of river snails
Shell, 50-60 part calcite, 45-55 parts of medical stones, 10-20 parts of bone meal mixing, 30-50min is toasted at 100-120 DEG C, is passed through
The ultrasonication 20-25min of 800-900W, obtains mixture；Mixture temperature is down to room temperature, is crushed as 80-100 purpose
Gained powder is uniformly mixed by powder with 300-500 parts of rotted pig manures, 200-300 parts of decomposed apple pomaces；The calcium is iron-based
The usage amount of fertilizer is 600-800kg/ mus；
The production method of step (2) the activation bacterial manure are as follows: in terms of quality point, by 5-8 parts of glucose, 0.4-0.6 parts of sulphur
Sour magnesium, 0.1-0.3 part calcium carbonate, 1.8-2.5 parts of calcium dihydrogen phosphates, 0.003-0.006 parts of iron chloride, 0.8-1 parts of glass powders,
980-1000 parts of water mixing, sterilize 3-5h at 120-140 DEG C, obtains culture；Culture temperature is down to room temperature, is inoculated with
0.5-0.8 parts of colloid bacillus cereus, cultivate 30-35h at 33-35 DEG C；By resulting culture solution and EM bacterium solution, biogas slurry, clear water
It mixes according to 1:3:30:800 up to the activation bacterial manure；The usage amount of the activation bacterial manure is 80ml/ plants.
The production method of step (3) the calcium iron flake leaven are as follows: in terms of quality point, by 0.5-1 parts of frerrous chlorides, 1-
3 parts of zinc chloride, 8-10 parts of potassium nitrate, 2-3 parts of calcium nitrate, 1500 parts of clear water mixed dissolutions.
The application method of the foliar fertilizer is to spray in early morning corn jointing stage, and the amount of spraying is 15-18kg/ mus.
Compared with prior art, technical effect of the invention is embodied in:
The present invention is using the higher shell of calcium iron content, river-snail sheil, calcite, medical stone, bone meal by drying and ultrasound
Wave smashes its texture structure, in favor of it is subsequent crushing and plantation in plasma diffusing W,Mo, then again with rotted pig manure, decomposed apple
Pomace is mixed to form whole weakly acidic mixture, and the mineral elements such as calcium abundant, magnesium, iron can be provided for corn, and
Organic matter rich in improves the liquid manure absorbability of soil；In addition, utilizing EM using activation bacterial manure when corn planting
Bacterium decomposes the organic matter in soil and forms nutritional ingredient, provides safeguard for the existence of colloid bacillus cereus, promotes colloid gemma bar
The iron-based fertilizer of bacterium accelerated decomposition calcium improves the ratio of the absorbable nutrients such as calcium, the iron in soil, promotes absorption of the corn to fertilizer efficiency.
The foliar fertilizer containing calcium iron finally is used in the corn jointing stage, does not have started photosynthesis, woods using the not strong corn of morning illumination
Between gas concentration lwevel it is high, oxygen is low, the probability that the ferrous ion in fertilizer is oxidized to iron ion is reduced, so that corn is to leaf
The soak time of leaven is longer, and absorption efficiency is higher, accelerates the accumulation of corn nourishment substance, improves the output and quality of corn.
