One, corn
1, a reasonable ratio: N: P2O5: K2O = 1: 0.53: 0.41
2. Principle of fertilization: Apply basic fertilizer, light seedling fertilizer, reaming joint and panicle fertilizer, and skillfully apply granular fertilizer.
3. Base fertilizer: 2000-3000 kg organic fertilizer, all phosphate fertilizer, one-third nitrogen fertilizer, all or one-half potassium fertilizer as base fertilizer or seed fertilizer. The ploughing can be applied once to the sowing ditch, so that the fertilizer is applied to a layer thickness of 10-15 cm. All costs can be used as base fertilizer.
4, mouth fat: mouth fertilizer application of the most economical and effective method of fertilization. The method of application of oral fat is mostly applied to acupuncture and acupoint application. Organic fertilizers, quick-release fertilizers (such as ammonium sulfate, potassium sulfate, ammonium phosphate) and fertilizers, applied depth 5-10cm. Fertilizer dosage is generally 2-5kg. Urea, ammonium bicarbonate, ammonium chloride and potassium chloride should not be used as mouth fat.
5. Top dressing: The remaining two-thirds of nitrogen fertilizer and one-half of potassium fertilizer are used as top dressing. Man-made culm, top dressing fertilizer within 10 days after jointing, topdressing agent and shovel syrup, weigh up to one-third of the nitrogen and potassium fertilizers as stalk manure, which can promote stem growth and promote young panicle differentiation; panicle fertilizer, the remaining nitrogen fertilizer before corn tasselling 10-15 days of application, there is a large number of grains to promote large, reduce the role of digestion and degradation, and late grain filling also has a good effect.
6, zinc fertilizer: Zinc deficiency can be applied to zinc fertilizer, commonly used zinc fertilizer is zinc sulfate and zinc chloride, base fertilizer wood dosage 0.5-2.5 kg, seed dressing dosage 4-5 g / kg, soaking concentration of 0.02-0.05%.
Second, rice
1. Reasonable ratio: N: P2O5: K2O=1: 0.62: 0.50
2. Principles of fertilization: promotion, control, and post-protection. That is, re-basal fertilizer, early application of sub-fertilizer, make-up panicle fertilizer.
3. Putian Fertilizer: Apply 5-10 kilograms of high quality brown coffee, 20 kilograms of nitrogen, 20 grams of phosphorus free oxide, and 20 grams of potassium oxide per square meter.
Putian base fertilizer, organic fertilizer, 50% nitrogen fertilizer, and all potash fertilizer are used as base fertilizer. After the target plate is well prepared, it is sown after the upper mud is leveled.
4, Honda Fertilizer: organic fertilizer applied about 3,000 kilograms, a large number of elements per acre can not exceed: pure nitrogen (N) 12-15 kg, phosphorus (P2O5) 6-7 kg, potassium (K2O) 12-15 kg; per acre Si 50 kg (acid soil area), zinc sulfate 1-2 kg (basic soil area).
During the Honda base fertilizer, organic fertilizer, silicon fertilizer, 50-70% nitrogen fertilizer, total phosphate fertilizer, 50% potassium fertilizer, and zinc fertilizer are used as base fertilizers. Nitroamine nitrogen fertilizer is not used as a base fertilizer.
The application method of basal fertilizer: (1) full-scale application, full-layer application of two methods. A full-layer fertilization method before the application of the bubble field, that is, the application of fertilizer to the field surface before soaking, and then the target field of the soaking field, preferably combined with rotary tillage, the fertilizer is mixed into the plough layer 7-10cm, then the field is soaked, and the plate is flattened; The second is a full-layer fertilization method in the back of the field, that is, in the bubble field and after the primary level, spread the fertilization material, and then apply the target fertilization material to mix with the plough layer weight, and then level the plate. Full-layer fertilization is characterized by long-term fertilizer and steady fertility. Because the fertilizer is distributed in the plough layer, it can promote deep rooting, enlarge the absorption area, and increase nutrient absorption. Full-layer fertilization also reduces fertilizer losses and improves utilization. (2) Spreading fertilizer, also known as surface fertilizer, spreading the fertilizer evenly over the surface of the leeches and then leveling the fertilizer so that the fertilizer is mixed with the surface layer, which is the main application method in rice production. The fertilizer is characterized by its rapid fertilizer effect, which is beneficial to the improvement of greening and tillering; the fertilizer effect is also relatively long, reaching about 45 days. When the amount of basal fertilizer is relatively small, it is advisable to use fertilizer for planting. After fertilization, as soon as the conditions of soil sedimentation permit, planting shall be carried out as soon as possible to reduce the loss of fertilizer. Can also be full-scale application, surface fertilizer combined, phosphorus and potassium fertilizer, 80% nitrogen fertilizer to do full-scale application, 20% of nitrogen fertilizer to do surface fertilizer.
Honda top dressing, according to the amount of basal fertilizer and seedlings to see seedlings, generally divided into tillers and panicles. 20-30% of the total nitrogen topdressing fertilizer should be used as a tiller fertilizer. The tillering fertilizer should not be late as soon as possible, and should be applied 3-7 days after transplanting. The panicle fertilization promotes the application of the flower fertilizer 3 days after the panicle is differentiated; the preserved fertilizer is applied 7 to 14 days after the panicle differentiation. 70-80% of nitrogen fertilizer and 50% of potassium fertilizer can be divided into two applications. First, when jointing, strong culm and flower growth, mainly to see the situation of leaf color fading to determine the top dressing; the second time can be in the inverted 2 leaves twitching, down When the tip of a leaf is applied, it is mainly to protect the flower, pay attention to the application of nitrogen and potassium fertilizers.
Third, soybean
5, 1, a reasonable ratio: N: P2O5: K2O = 1: 1.5: 1.5
2, fertilization principles: re-base fertilizer, clever application of top dressing.
3. Soil conditions: Soybeans do not have strict soil requirements, and have strong adaptability to soil texture. Soils with deep soil and rich organic matter are most suitable for soybean growth. Soybeans require neutral soil, and the pH is between 6.5-7.5. . Soybean is not salt tolerant.
4. Basal fertilizer: Based on basal fertilizer, 2000-3000 kilograms of high-quality organic fertilizer is applied in Mushi, and a certain amount of fertilizer is applied. Superphosphate 20-30 kg (diammonium 8-10 kg), potassium sulfate 10-12 kg. The land with high fertility should be reduced by 2 kg.
5, seed fertilizer: According to local conditions, you can choose trace elements fertilizer dressing. Ammonium molybdate: 0.5 grams per kilogram of bean seed, seed dressing concentration of 0.5%; borax: 0.4 grams per kilogram of bean seed, seed dressing concentration of 0.05%; zinc sulfate: 2-4 grams per kilogram weight, concentration of 0.1%. Dry after sowing. 5-8 kilograms of diammonium can be used as the manure, pay attention to the isolation of the fertilizer.
6, top dressing: generally at the beginning of flowering nitrogen fertilizer (flowering 5 days before the role), chase 3-5 kg ​​of urea, superphosphate 8-10 kg, potassium sulfate 3-5 kg, can protect the soybean production. The method is to spread the fertilizer on one side of the soybean plant, or fertilize the plant 5-10 cm away from the plant, then cultivating the soil. Seedlings found weak and yellow seedlings, can be an appropriate amount of nitrogen supplement.
7. Top-dressing: spray once, from early flowering to full flowering: spray twice, first at the early flowering stage, and secondly at the final flowering stage until the early flowering stage. Spray fertilizer selection: urea 0.6 kg, potassium dihydrogen phosphate 100 grams, 100 grams of borax, 10 grams of ammonium molybdate, 200 grams of zinc sulfate, fertilizer can be sprayed alone, but also according to the situation of several mixed spray.
