The nature of no-tillage fertilizer and its use on vegetables

First, the nature of no-tillage

1. Fertilizer properties

The nutrient composition of no-tillage fertilizer is firstly a large amount of available elements such as nitrogen, phosphorus and potassium in a quick-acting state, with a total content of 30%; followed by a variety of important intermediate and trace elements, such as sulfur content of 9%, calcium, magnesium and iron. The total content of trace elements in copper, molybdenum, zinc, manganese and boron is 1%. It can be said that the nutrients are balanced and comprehensive. It should be noted that these nutrients are in the most easily absorbed ionic state, in which the metal trace elements are 100% chelated. No-till fertilizer also specially added anti-reverse factors and quality improvers, which can effectively improve the ability of crops to resist disease, cold, drought, salt and alkali, and dry heat.

2, no-till properties

The no-tillage fertilizer is rich in soil conditioners such as soil aggregate structure promoters and soil particle activators. The use of the fertilizer can improve the soil, prevent soil compaction, fully activate soil nutrients, improve soil aggregate structure, improve soil water, fertilizer, gas and heat conditions, increase soil microbial vigor, and alleviate some diseases transmitted through the soil; In the case of less tillage and no-tillage, the crops can thrive and avoid problems such as soil compaction and deterioration caused by long-term use of common fertilizers.

Second, the characteristics of no-tillage fertilizer

1. No-tillage fertilizer is rich in large, medium, trace and rare elements needed for crops, and special activities are added to promote crop growth and fruit expansion and induce disease resistance and stress resistance, nutrient-rich, balanced, and proportioned science. .

2, no-tillage can improve soil particle structure, prevent compaction, reduce soil-borne diseases, increase the soil's beneficial microbial vigor, so that the soil environment can adapt to the healthy growth of plants, in one fell swoop.

3, no-tillage can promote the growth of roots, induce rooting, so that root activity is significantly enhanced, can prevent bad roots, roots, roots and other undesirable phenomena, improve resilience.

4. No-tillage can promote the growth of fruit trees, induce flower bud differentiation, preserve flowers and promote fruit; promote fruit development and expansion, prevent and reduce symptoms such as cracked fruit, heart rot, umbilical rot, deformed fruit and small fruit, thus making the fruit shiny and beautiful. The increase in production is obvious.

5. No-tillage fertilizer is specially added with anti-disease factors and quality improvers, which can effectively improve the ability of disease resistance, cold resistance, drought resistance, salt and alkali resistance, dry heat resistance and other adverse environmental factors, and prevent vegetable leaves and yellow leaves. Physiological deficiencies such as curling leaves, shrinking leaves, and fallen leaves; and improving biological enzyme activity, leaf thickening, chlorophyll increase, and photosynthesis enhanced. At the same time, the color is sweetened, the flavor is strong, the storage is good, the quality is good, and the benefit is high.

6. No-tillage fertilizer also has the function of killing insects and saving irrigation water. No-tillage fertilizer can not only kill the pests in the soil. Moreover, no-tillage fertilizer absorbs and stores in the roots of crops, so that the water is not easy to evaporate and infiltrate into the ground, which can save more than 50% of irrigation water, and has obvious effects of protecting moisture and drought. This will play an active role in coordinating the promotion of the national conservation tillage demonstration project, contributing to reducing wind erosion, water erosion, soil fertility and drought resistance.

Third, the application of no-tillage fertilizer

1, applicable objects

Various crops, including grain, cotton, oil, soybeans, fruits, vegetables and various medicinal materials, tea, flowers and other economic crops.

2, the practical effect of no-tillage fertilizer

The no-tillage fertilizer is suitable for various crops and various types of soil; it can be used as a fertilization fertilizer, and can also be applied as a top dressing by foliar application, ditch application, acupoint application, root application, and soil mixing as a base fertilizer. It is more effective in the application of leafy vegetables, especially greenhouse vegetables.

3, no-till fertilizer use

No-tillage can be used in a variety of ways, such as flushing, acupoint application, base application, root irrigation, drip irrigation, and foliar application.

Note: (1) Foliar spraying should be carried out after a small range test before confirming the best use concentration;

(2) When the crop is young or sprayed at the seedling stage, low concentration should be adopted to avoid adverse consequences.

4. Usage and dosage of no-till fertilizer

(1) Fruits. Such as pears, apples, etc., according to the size of the tree and the tree potential, the application of points, 50 ~ 150 grams per plant; can also be diluted 300 ~ 800 times foliar spray, generally 2 ~ 3 times, interval 7 ~ 10 day.

(2) Fruits, vegetables and other crops. In the seedling stage and initial stage, 4~8 kg per acre is used, and in the middle and late stage, 8~10 kg per acre is used, and it can be applied once every 10~15 days. It can also be applied by acupuncture, root application and foliar application.

5. Application of no-tillage fertilizer on vegetables

It is used on leafy vegetables, generally effective in 3 days, leaves are dark green and grow well. When applying fertilizer, it is applied with water (drip irrigation, watering, rooting, etc.), high nutrient concentration, good water solubility, nutrients are not easily fixed by soil, and can be absorbed by crop roots in time, the effect is obviously better than common fertilizer and compound Fertilizer soil application (application of fertilizer to the soil); in drip irrigation, watering, rooting, etc., the best drip irrigation effect. When applying ditch, hole application, root application and soil application as base fertilizer, the dosage per acre is 4~20 kg, which is better than common fertilizer and compound fertilizer, and it saves labor and labor, and can prevent soil compaction. When crops urgently need nutrients, foliar spraying or watering can be balanced, fast, efficient, and safe to meet the needs of crops, and also prevent soil compaction.

5, no-till fertilizer use precautions

(1) Do not mix with alkaline fertilizers.

(2) No-tillage fertility is sufficient and cannot be used excessively.

(3) No-till fertilizer is not mixed with pre-emergence herbicides.

(4) When no-tillage fertilizer is applied for foliar application, the appropriate application concentration should be selected according to different growth periods and different environmental conditions of different crop varieties.

(5) If the no-tillage fertilizer has agglomeration, it will not affect the use effect.
