The Jianchuan potato soil testing formula fertilization technology, potato is an indispensable dish in daily life, the market demand is large, planting has a good development prospect, how to improve the potato yield is a concern. Potato soil testing formula cultivation is based on the determination of soil nutrient and fertilizer efficiency test. According to the fertilizer requirement of potato, a scientific formula and measures for determining the scientific formula and measures are beneficial to increase the yield of potato.
Potato Soil Testing Formula Fertilization: Scientific Formula
The scientific formula is the core of potato soil testing formula cultivation, and it is the key to achieve the best cultivation benefit. By calculating the soil sample measurement data and the results of the four groups of fertilizer test results that have been completed, and considering the previous production experience, combined with the expert group correction, The target yield and fertilization formula determined are as follows:
- 1. Target production, more than 2500 kg per mu, fertilization formula is: 2000-2500 kg of organic fertilizer, 15-20 kg of urea, 70-90 kg of calcium, 12-15 kg of potassium sulfate.
- 2. Target production, when the yield is 2000-2500 kg per mu, the fertilization formula is 2000-500 kg of organic fertilizer, 14-18 kg of urea, 60-80 kg of calcium, and 10-12 kg of potassium sulfate.
- 3. Target production, when the yield per mu is 1500-2000 kg, the fertilization formula is 2000-500 kg of organic fertilizer, 12-16 kg of urea, 50-70 kg of calcium, and 8-10 kg of potassium sulfate.
The organic fertilizer in the formula is applied as the base fertilizer, 30% of the urea is used as the seed fertilizer, 10-20% of the urea is applied as the seedling fertilizer, and 50-60% of the urea is used as the tuber swelling fertilizer before the sealing, potassium sulfate 50% is applied as a seed fertilizer, 50% is applied as a tuber swelling fertilizer, and calcium is applied as a seed fertilizer.
Potato soil testing and formula fertilization: plot selection
The potato granules are tubers that grow underground. They are good for irrigation and are rich in organic matter. The pH value is 5.5-7.0 in loam or red soil. Therefore, the plot should be high in soil ripening, fertile and deep. In sandy loam or loam, the potato is a Solanaceae crop. It should not be rotated with flue-cured tobacco or pepper, and should be rotated with legume or grass crops.
Potato soil testing and formula fertilization: soil preparation and fertilization
Before planting, it is necessary to cultivate the land early, and the depth of ploughing should be more than 30 cm. It should be fully sun-dried, especially the small spring potato cultivated in the field of the dam area, combined with the broken sorghum, and strive to make the field flat, fine, soft and clean. After the field is completed, the planting ditch should be opened at a line spacing of 80 cm. If it is cultivated in the field, it is necessary to manage the ditch for irrigation and drainage.
Applying the base fertilizer and organic fertilizer as the base fertilizer, it is concentrated in the seeding ditch. The calcium in the fertilizer, 30% in the urea and 50% in the potassium sulfate are applied to the seed potato, but cannot be contacted with the seed potato. In order to avoid burning seedlings,
[Remarks] The soil conditions are different in different places. The specific fertilizer requirements should be adapted to local conditions. The above is the whole content of Jianchuan potato soil testing formula cultivation technology. Potato is the main crop in mountainous area, which is not only food but also vegetables, which is rich in people's dishes and poverty alleviation in mountainous areas. To an important role, Jianchuan has high altitude, low temperature, and fewer potato pests, so the species is slow to degenerate and tastes good. For other local potato soil testing formulas, please consult the local agricultural technology department.
