Abstract
The invention relates to a corn planting method. The corn planting method comprises steps as follows: (1), soil preparation: the soil is deeply ploughed for 25-30 cm, the soil is leveled, and 80-100 kg of a corn compound fertilizer is applied for each mu of land and in the position 10-20 cm below the ground surface; (2), sowing: corn seeds are sown in rows, the sowing depth is 8-10 cm, the sowing space is 25*40 cm, 2-3 seeds are sown in each hole, and each hole is watered with a sodium bicarbonate water solution with the mass percentage being 5% after sowing; (3), pulling up of seedlings: when the seedlings grow to 20-25 cm, the seedlings with poorer growth vigor are pulled up from each hole, and one seedling is reserved in each hole; (4), daily management: weeding and watering are performed at fixed time. According to the corn planting method, through rational close planting during planting of corn, corn ventilation is facilitated, the corn yield cannot be affected by excessive sparsity and can be increased, sodium bicarbonate water is used for watering during planting, and accordingly, the corn germination rate can be increased.
Description
Technical field
The invention belongs to fertilizer field, be specifically related to a kind of corn planting method.
Background technology
Corn nearly more than 470 years at the cultivation history of China.Current China sown area, at about 300,000,000 mu, is only second to paddy and wheat, occupies the 3rd, be only second to the U.S. in the world in food crop.The torrid zone, the whole world and Temperate Region in China are extensively planted, and are an important cereal.Taste is fragrant and sweet, can do various dish, as corn irons.Also be the main raw material of industrial spirit and liquor.During corn planting, the bud ratio of corn and corn yield are not high, and utilization rate of fertilizer is also lower.
Summary of the invention
The object of this invention is to provide a kind of corn planting method, not only can promote the output of corn, also there is the effect that insect protected is disease-resistant, and can not soil compaction be caused.
The present invention is achieved through the following technical solutions:
A kind of corn planting method, comprises the following steps:
(1), wholely, deep ploughing soil 25-30cm, flattened by soil, corn composite fertilizer 80-100kg is used on every mu of ground, and Term Fertilization is 10-20cm under earth's surface;
(2), sow, sow by row, depth of planting is 8-10cm, and seed spacing is 25*40cm, every bunch planting kind 2-3, and after planting, the sodium bicarbonate aqueous solution 30-40ml of massfraction 5% is watered in every cave;
(3), carry seedling, carry when seedling grows to 20-25cm the seedling that in every cave, growing way is more weak, keep every cave to leave a strain seedling;
(4), daily administration, timing is carried out weeding, is watered.
Preferably, described corn composite fertilizer is made up of the raw material of following weight part:
Urea 35-42 part, potassium sulfate 12-15 part, Calcium hydrogen carbonate 15-18 part, waste of flax carbon 12-15 part, boric acid 0.5-1 part, Trisodium Citrate 1-1.5 part, manganous sulfate 1.2-1.5 part, ammonium molybdate 0.8-1.5 part, soya sauce 12-15 part, dextrin 10-15 part, Chinese medical extract 1.5-2 part;
Described Chinese medical extract is made up of following raw material by weight: Semen Euphorbiae 3-5 part, Wu Chia Pee 2-4 part, dark plum 1-3 part, pomegranate rind 12-15 part, saltcake 4-6 part, Perilla Stem 3-5 part, Herba Phyllanthi Urinariae 5-8 part, Rhizome of Decumbent Corydalis 1-2 part, Yunnan Caulis Spatholobi 2-4 part.
Further, the preparation method of described corn composite fertilizer comprises the following steps:
(1), Semen Euphorbiae, Wu Chia Pee, dark plum, pomegranate rind, saltcake, Perilla Stem, Herba Phyllanthi Urinariae, Rhizome of Decumbent Corydalis, Yunnan Caulis Spatholobi are added Chinese medicine weight 8-10 soak by water 1-2h doubly, then squeezing is filtered, obtain filtrate and filter residue, filter residue is dried, be broken into 80 object dregs of a decoction powder, filtrate be condensed into the paste Chinese medical extract of relative density 1.25-1.3 at 25 DEG C;
(2), by the paste Chinese medical extract that step (1) is obtained mix with soya sauce, dextrin, waste of flax carbon, Trisodium Citrate, use ultrasonication 10-15min;
(3), by the mixture that the dregs of a decoction powder of urea, potassium sulfate, Calcium hydrogen carbonate, boric acid, manganous sulfate, ammonium molybdate and step (1), step (2) obtain mix, granulation, obtains composite fertilizer.
Soya sauce is common commercially available soya sauce, can provide the nutritive elements such as amino acid, is easy to fertilizer bonding simultaneously.
Beneficial effect of the present invention: corn planting method provided by the invention is by the rational close planting when corn is planted, both be conducive to corn to ventilate, again can not the too sparse output affecting corn, the output of corn can be promoted, when planting, use sodium bicarbonate water waters, the germination rate of corn can be promoted, and corn composite fertilizer of the present invention adopts the mode adding Chinese medical extract and other organic compositions in mineral manure, not only can provide good nutritive element for corn, and be conducive to insect and the root disease of corn prevention root, promote the Yield and qualities of corn, and can not soil compaction be caused, waste of flax carbon is added in fertilizer, Chinese medical extract etc. is made to immerse waste of flax carbon pores gap through excusing from death process, realize slowly-releasing, fertilizer efficiency and pest-resistant can be extended, the disease-resistant cycle.
