常见疑问
Common Questions from Farmers
你说你家肥料好，但是我都施用半个月了也没啥效果，长势还不如别人的，这是不是假肥料啊？
You said your fertilizer is good, but I’ve been using it for half a month with no visible effect. My crops grow even worse than others’. Is this fake fertilizer?
我用你的肥料这么长时间，长势没啥变化，隔壁老王用的另外一家的肥料，人家刚用2天，长势呼呼的，你的肥料是不是有问题？
I’ve used your fertilizer for quite a while but see no change. My neighbor used another brand for just two days, and his crops are growing fast. Is there something wrong with your fertilizer?
农资经销商经常遇到这样的问题，甚至有些农资店老板也开始怀疑：难道这次真的碰上假肥料了？
Agricultural input dealers often face such doubts. Even some store owners start to wonder: “Did we really get fake fertilizer this time?”
见效快的肥料未必是好肥料
Fast-Acting Fertilizers Are Not Necessarily Good Fertilizers
“见效快就是好肥料”，很多农民固执地认为。这其实是严重的误区。
“The faster the effect, the better the fertilizer”—this is a common but serious misconception among many farmers.
肥料需要长期供应，最好根据作物的生理阶段合理配比施用，没有必要盲目追求速效性。
Fertilizers should provide long-term nutrients, applied according to the crop’s growth stage, rather than blindly chasing quick results.
一些不法厂家会在肥料中添加激素或劣质氮肥，使作物短期内长势旺盛，但往往导致花芽分化差、早衰、减产。
Some unscrupulous manufacturers add hormones or low-quality nitrogen fertilizers. Crops may look vigorous in the short term but suffer poor flower differentiation, early aging, and lower yields.
常见肥料见效时间（仅供参考）
Reference: Fertilizer Effect Onset Time
-
碳铵：当天见效，肥效期约15天
Ammonium Bicarbonate: Effective the same day, lasts about 15 days -
氯化铵：3天见效，肥效期25天，后期易脱肥
Ammonium Chloride: Takes 3 days, lasts 25 days, prone to nutrient loss later -
尿素：7天见效，肥效期45天
Urea: Takes 7 days, lasts 45 days -
复合肥：10天见效，肥效期90天
Compound Fertilizer: Takes 10 days, lasts 90 days -
生物肥：约1个月见效，肥效可持续6–8个月
Bio-fertilizer: Around 1 month to show results, lasts 6–8 months -
激素类物质：见效快，但营养有限，对增产帮助不大
Hormonal Substances: Very fast, but little nutrition, not truly beneficial for yield
为什么生物肥见效慢？
Why Do Bio-fertilizers Take Longer to Work?
生物肥的菌种需要时间适应土壤环境并繁殖，温度较低时作用更慢。部分作物使用生物肥后，前期长势甚至不如常规肥。
Microbes in bio-fertilizers need time to adapt and multiply in the soil. At lower temperatures, this process is even slower. Some crops may initially grow weaker than with conventional fertilizers.
但随着根系更强健，后期往往能带来更高产量和更好品质。
However, stronger root development in later stages usually leads to higher yields and better quality.
用肥原则
Principles of Fertilizer Use
作物生长规律是：前期生根 → 中期长茎叶 → 后期结果。若盲目追求茎叶旺长，忽视根系和结果，最终只会早衰减产。
Crop growth follows a natural law: root development in early stage → stem and leaf growth in mid-stage → fruiting in later stage. If you push for lush leaves at the wrong time, roots and yields will suffer, leading to early senescence.
真正的好肥料是 保证产量和品质，而不是单纯“见效快”。
A truly good fertilizer ensures yield and quality, not just “quick effects.”
提高肥料利用率的方法
Ways to Improve Fertilizer Efficiency
化学肥料利用率并不高：稻谷对氮肥利用率约50%，磷肥仅20–30%。有机肥配合深层施肥，可以显著提高吸收率。
Chemical fertilizers have low efficiency: rice uses about 50% of nitrogen, and only 20–30% of phosphorus. Combining organic fertilizers with deep application greatly improves utilization.
深层施肥方式
Deep Fertilization Methods
-
耕田深施：排水 → 撒肥 → 犁翻耙平 → 插秧
Plow-Deep Application: Drain water → spread fertilizer → plow & level → transplant rice -
面层深施：插秧前最后一次犁翻后撒肥，再耙田 → 插秧
Surface-Deep Application: Spread fertilizer after last plowing → level field → transplant -
球肥深施：化肥+泥水制成球肥（约100克），塞入禾苗间7–10厘米深
Fertilizer Ball Application: Mix fertilizer with mud → make balls (~100g) → place 7–10 cm deep between seedlings -
液体深施：化肥或农家肥配制肥液，用施肥器灌入10厘米土层
Liquid Deep Application: Dilute fertilizer with water → inject about 10 cm deep using applicator
其中以 球肥深施效果最好，尤其适合作为追肥。
Among these, fertilizer ball application works best, especially for topdressing.
要点总结：
不盲目追求见效快 → 科学施肥 → 保障产量与品质。
Key Takeaway: Don’t blindly chase quick effects → Apply scientifically → Ensure yield & quality.
