Flowers and foliage fertilizer for agricultural silicone additives

After years of foliar fertilizer application, the effect has been overwhelming majority of workers approved. But the current knowledge on fertilizer is too simple and unilateral, some operation is not standardized, especially in the production of flowers and trees, not in accordance with the characteristics off lowers itself will make full use of. And with the development of science and technology, different kinds of leaf fertilizer on the market began to emerge in large numbers. How to choose according to need of foliar fertilizer and how to operate in order to get the highest efficiency is the key problem of the rational use of foliar fertilizer. In this regard, the special the foliar fertilizer about principle and application technology are briefly introduced as follows, for reference:

The advantages, disadvantages, a foliar fertilizer

1 advantages

(1): the first, with the popularity of economic and effective pest control work, the addition of foliar fertilizer on the use of pesticides, fungicides at the same time, is quite effective and economic method of operation.

Second, the use of foliar fertilizer added leaf nutrition, high economic benefit,saving fertilizer. Such as about the phosphorus, potassium and trace elements content is only equivalent to other soil topdressing amount 10%.

Third, because it can directly supply the effective nutrient solution of flowers and trees, the adsorption of soil fixed, and then make the problem of low effective nutrient.

(2) quick: nutrient absorption of fast, high utilization rate, can promptly satisfy the need. For example, application of urea in the soil usually takes 4 to 5 days to bear fruit, but foliar spraying can be 1 to 2 days to see the results. So in the prevention and treatment of deficiency is generally uses the out root fertilization,the effect is very good.

(3) the use of the environment: in general, the strict requirements on a windless,no rain, no fog weather can. And in the dry weather, no rain and nutrient availability is low, foliar fertilizer is added in a timely manner in urgent need of nutrition is the most effective, the most economical fertilization method.

(4) extensive role: one is to supplement the nutrition of tree body, used to promote healthy growth of flowers and trees of dressing method.

Two is timely, effectively solve various nutrient deficiency diseases, is a necessary means to maintain tree health.

The three is to solve the growth of flowers and trees, drought and water logging late after the need to repair the tree root activity decreased body lead to the most direct and effective method to reduce the problem of nutrient absorption.

2 disadvantages (1) provides a limited number of foliar nutrient absorption of nutrients: the penetration rate is low, the absorption quantity is less, the blade especially thick cuticle, not enough to meet all the needs of crop, especially a large number of elements of nitrogen, phosphorus, potassium. Therefore, foliar fertilizer can be used as auxiliary measures of dressing.

(2): fertilizer topdressing fertilizer short relative to the other way, its effect is quite short, especially in the supplement is not easy to move the elements, this show will be more prominent. For example: iron deficiency, the interval of 5 to 7 daysof spraying time. Otherwise, there will be symptoms of iron deficiency.

(3) easy to drain: first, in the spraying process, if the improper operation or in windy weather, easy from leaf drop, waste liquid.

Second, the rain is easy to leaching, under normal circumstances, 4 hours after the heavy rain to spray.

Third, if the weather is too dry, liquid medicine in rapid drying effect of foliarabsorption, thereby affecting the efficiency.

(4) easy to produce fertilizer damage: because the characteristics of blade itself,its resistance to liquid root much worse. If the use of concentration, the use oftime, interval time and so on choice of improper and unreasonable easily causeleaf burn.

Two, foliar absorption characteristics principle and flowers and trees

The absorption of nutrients to the general principle: a molecule or ion form through the sto mata and cuticle into the leaf phloem, participate in various physiological cycle of flowers and trees, in order to promote the various physiological activities, to promote and regulate plant growth objective. And according to the principle of the nearest transport nutrients in leaves, leaf fertilization are conducive to the growth of plant growth center.

The 1 characteristic of the flowers and trees: Seedling itself can store some nutrition, in normal environment and tree, its coordination function for it'snutrition. So, sometimes on the use of strong seedling tree foliar fertilizer after effect is not very obvious, but there is still the role, in a certain sense can increase tree body nutrition accumulation, maintains the tree body strong.

2 fertilizer requirement characteristics: the embryonic period is usually on tree sto supply nutrition. So, in the bud, in a sensitive period is not recommended, so as not to interfere with the physiological cycle of its own, produce fertilizer harm.With the leaves unfold, fertilizer absorption crescendo. When absorption growth to reproductive growth when nutrients up. With growth weakening, absorption decrease. To absorb the lignified after weak.

The longer growth period of 3 seedlings, there should be a certain time intervalin the growing period, and selectively top dressing, but also should pay attention to dressing too much can cause seedlings leggy seedlings, is not conducive tothe winter, then the impact of second years of growth and development.

The following points are noteworthy: 1 germination of new leaves sprout, general and normal leaf compared to more yellow green, this is not a sign of lack of fertilizer. You can use the foliar fertilizer, but must pay attention to the concentration, especially some sensitive species, varieties, according to the specific situation of lower concentration or not, in order to avoid injury, affect the normal growth of new leaves.
