Silicon fertilizer is a kind of mineral fertilizer containing calcium silicate, which is second only to nitrogen, phosphorus and potassium. In 1955, Japan began to produce and use silicon fertilizer, which became one of the important fertilizers in agricultural production. It was introduced to China in the early 1990s. In 2004, the Agricultural Bureau of Shanting District of Zaozhuang City introduced the technology of using silicon fertilizer into the test application of summer corn field. After investigation and test on Chenhu Village, Sangcun Town, Sangcun Village and Yuzhuang Village of Chengtou Town, the output was 760 kg per 667 square meters. Create the best level of corn production history in the region. The specific practices are now described as follows:
First, the selection of good varieties, reasonable close planting selection of high-yield varieties Ludan 984. According to the test, in the comparison test of 24 corn varieties, Ludan 984 increased yield by 70.5 kg per 667 square meters compared with the control species, the yield increased by 13.8%, and the seedling density per 667 square meters was 4000-4500.
Second, the implementation of nitrogen, phosphorus, potassium, silicon formula fertilization in the case of not calculating the ground force, for every 50 kg of corn produced, need to invest 1.25 kg of pure nitrogen, 0.5 kg of phosphorus pentoxide, 1 kg of potassium oxide, 0.75 kg of dioxide silicon. According to the planned output of 800 kg, 20 kg of pure nitrogen, 8 kg of phosphorus pentoxide, 16 kg of potassium oxide, 12 kg of silica, and 2 kg of zinc sulfate are used for every 667 square meters. Fertilization period and method: generally used three times of seedling fertilizer, panicle fertilizer and granular fertilizer. Miao Fei: In the 6-7 leaf stage after Dingling, all phosphorus, potassium, silicon, zinc fertilizer and 30% nitrogen fertilizer were applied. Ditch 10 to 15 cm on both sides of the seedling, the depth of the ditch is 10 cm, and spread evenly. Spike fertilizer: in the 11 ~ 12 leaf stage, 35 days after sowing, 15 ~ 20 cm from the plant, 60% of the nitrogen fertilizer. Granular fertilizer: 10% of the nitrogen fertilizer is applied during the tasseling period. At this time, it is in the flood season and can be applied. According to the silicon fertilizer test in the high-yield corn field of Chenhu Village, Chengtou Town, the Shifang District increased the yield of corn by 96 kg per 667 square meters compared with the control area, increasing production by 20.4%.
Third, timely prevention of pests and diseases
1. Seedling stage: mainly to control corn borer, spodoptera, spiny worm, zinc deficiency. 1 Combine the weeds in the field to remove the weeds in the field, and timely burn the weeds and diseased plants to reduce the source of insects. 2 Spray with 40% dimethoate or 40% omethoate EC 2000-3000 times to control corn borer and treat gray planthopper. 3 using a 0.2% to 0.3% zinc sulphate solution per acre 25-30 kg in the corn 4 to 5 leaf foliar spray to prevent zinc deficiency, enhance plant disease resistance.
2, heart leaf stage and ear stage: to control corn borer, armyworm, sheath blight, leaf spot disease, and treat corn borer, thrips and so on. 1 Strengthen field management, timely weeding and weeding, rational fertilization, and increase application of phosphorus and potassium fertilizer to improve the plant's resistance. In the 2 large bell mouth period, the corn mites were controlled with chlorpyrifos No. 1 granules and 0.3% phoxim granules. 3 Control the armyworm with 90% trichlorfon 1000 times solution or 50% dichlorvos 2000 times solution and 40% dimethoate 1500 times solution. 4 spray with 70% thiophanate or 50% carbendazim WP 500-800 times to prevent sheath blight and leaf spot.
4. The suitable harvest of Ludan 984 is compact, and the mature characteristics of compact corn are pseudo-maturing. The leaves of the ear turn white, the stems and leaves remain green, and the maturity is not mature. When the base of the seed appears black line, milk The line begins to disappear, and when the leaves are loose, they indicate maturity and can be harvested.
