Abstract
The invention discloses a sweet potato cultivation fertilizer formula, which involves: 95-105 parts of ammonium sulfate, 240-250 parts of urea, 55-65 parts of monoammonium phosphate, 95-105 parts of calcium superphosphate, 5-15 parts of a calcium magnesium phosphate fertilizer, 315-325 parts of potassium sulfate, 10-20 parts of amino acid chelated molybdenum, zinc, manganese and boron, 95-105 parts of nitro humic acid, 17-27 parts of a biological agent, 7-17 parts of a synergistic agent, and 15-25 parts of a conditioner. The formula can promote root water uptake in rooting rejuvenation period, accelerate the sweet potato early stage growth speed, and reduce field water evaporation. Slow release of the contained nutrients can prevent flourishing growth of sweet potato stems and leaves, and promote sweet potato tuberization, thus increasing dry farming sweet potato yield.
Description
Technical field
The present invention relates to the preparation of the fertilizer formula that sweet potato is cultivated, the fertilizer formula that especially a kind of sweet potato is cultivated.
Background technology
Sweet potato, another name pachyrhizus, Ipomoea batatas, sweet potato, yam etc.Sweet potato genus convolvulaceae sweet potato genus is overgrow herbaceous plant.Sweet potato, in the evergreen growth of subtropical and tropical zones energy, is perennial plant, but meets frost death in place, temperate zone, is yearly plant.
Sweet potato is very extensive in China's cultivated area, almost throughout the whole nation.
The nutrient uptake feature of sweet potato
Sweet potato is a kind of high-yield crop, and vegetative period is longer, well developed root system, and fertilizer sucting ability is strong, and fertilizer requirement is large.In breeding time from the Main Nutrients potassium element of soil absorption at most, nitrogen takes second place sweet potato, and phosphorus is less, and sweet potato is happiness potassium crop.According to the study, often produce 1000 kilograms of fresh sweet potatoes and need absorbed nitrogen (N) 3.5 ~ 4.2 kilograms, phosphorus (P
2o
5) 1.5 ~ 1.8 kilograms, potassium (K
2o) 5.5 ~ 6.2 kilograms, its assimilation ratio is about 1: 0.4: 1.5.The absorbed dose of different growing to three large nutrient elements of sweet potato is not identical yet, the absorbed dose of general nitrogen to grow early stage, mid-term be many, mainly to grow for cauline leaf; When cauline leaf grows into the Sheng phase, peak to the absorbed dose of nitrogen, the absorbed dose of late growth stage to nitrogen starts to reduce; The potato block expanding stage that is absorbed in of phosphorus element is increased to some extent; To potassium element to be absorbed in whole breeding time all many than nitrogen, phosphorus, especially potato block expanding stage, absorbed dose peaks.Potassium expands to promotion potato block and the accumulation of acceleransstoff plays an important role, and to late growth stage, block root is contained long, and cauline leaf growth degradation, declines to the absorbed dose of nutrient, and shift to block root.
Sweet potato fertilizer practice
1. the base manure growth of sweet potato phase is longer, and output is high, needs based on enough base fertilizer, and base fertilizer foot just can make sweet potato growth in mid-term, and mid-term, fertility was steady, and the not de-fertile and early ageing of Later growth, to protect good quality and high output.Sweet potato is ridge planting, and base manure focuses mostly on and executes in ridge, at the bottom of bottom to ridge.Base manure, based on fertilizer, coordinates appropriate inorganic fertilizer.
2. topdress general point of short seed manure, strong strain is urged potato fertilizer, is urged potato fertile.
(1) short seed manure.Within 15 ~ 20 days after planting, carry out, object impels cauline leaf early to send out.
(2) potato fertilizer is urged in strong strain.Strong strain within 45 ~ 60 days, should be executed after planting and urge potato fertilizer, with short knot potato, early seal ridge.
(3) short potato is fertile.Generally within 80 ~ 100 days after planting, use, execute special fertilizer for sweet potato 15 ~ 20 kilograms or 10 ~ 15 kilograms, ammonium sulfate, potassium sulfate 10 ~ 15 kilograms for every mu.Fertilizer can be watered to fill with to be executed in the crack of the ridge back of the body.
3. foliage top dressing is in the growth of sweet potato later stage, the reduced capability of Root Absorption nutrient, in order to protect cauline leaf to grow, prevents plant early ageing, can foliage-spray containing urea, potassium primary phosphate and various trace elements
agriculture sea boardamino acid foliage fertilizer, every about 10 days once, and general spray 2 times, has positive effect to sweet potato good quality and high output.
Summary of the invention
The object of this invention is to provide the fertilizer formula that a kind of sweet potato is cultivated.
The fertilizer formula that this sweet potato is cultivated, is formed by following substance weight part is mixed: fertilizer is nitrogen, the large constituent content of phosphorus, potassium three is the formula of 35%:
95 ~ 105 parts, ammonium sulfate, 240 ~ 250 parts, urea, monoammonium phosphate 55 ~ 65 parts, calcium superphosphate 95 ~ 105 parts, 5 ~ 15 parts, fused(calcium magnesium)phosphate, potassium sulfate 315 ~ 325 parts, amino acid chela (network) close molybdenum, zinc, manganese, boron 10 ~ 20 parts, nitro humic acid 95 ~ 105 parts, biotechnological formulation 17 ~ 27 parts, synergistic agent 7 ~ 17 parts, amendment 15 ~ 25 parts.
