Big because of the big production investment, in order to reduce the risk, in the selection of fertilizer will not be blind, will choose the test, the effect of stable fertilizer. Moreover, because the agricultural product market is more secure, and retail investors pay attention to the season of harvest is different, they are more valued multi term income, and therefore have a long-term vision in the selection of fertilizers.
The cost of planting 1000 acres of lotus 200~300 million / year, so in all aspects of production should be kept under strict security. Anhui planting lotus boss said: "like your lotus special fertilizer belongs to a new product, we recognized, need to use a part of the test you, and see what effect it has. The first year is not a large area of use, so that can reduce the risk of." He said the risk, on the one hand refers to the impact on yield, more influence on soil health, will not lead to replant disease. The lotus root is a small crop, few studies on fertilizer requirement regularity, many farmers don't understand scientific fertilization, cause more serious lotus replant disease commonly planted a few years after production. He told us that he has another nine years this year, output is maintained in 4000 kg / mu around. Other farmers to the output of the third and fourth years already amounted to less than this number, a lotus root can only change the plots.
Annual overall plan for the whole year -- fertilizer application in different stages of Citrus
As a whole, it is very important for crop growth, especially in the general growth cycle of economic crops, and the effect of sub fertilization is needed. Planting 15000 acres of Citrus clock the boss said: "don't look at my big area orchard, extensive management, tree and many weeds, but fertilization not lazy not only applied organic fertilizer, different period also application packages of Citrus fertilizer. Fruit trees to eat good enough, to give me work." Citrus fertilizer the key three times, the base fertilizer in autumn to balance type based, spring fertilizer with high nitrogen, summer expanding fruit fertilizer with high nitrogen and high potassium, clock the boss not only application at different stages of development of the formula like the palm of his hand and on how to use, the number of facilities is clear.
Research found that the difference in the levels of lotus root yield larger, from Anhui Changfeng County, a lot of per mu 2000 pounds to Hanchuan City, Hubei Province, 5000 kg range, main difference is whether the reasonable fertilization. Hanchuan major than Anhui's focus on late fertilization, to avoid late off fat. Changfeng planting lotus is dominated by retail, because the lotus leaf covered with outian fertilizer after difficulty increases, most farmers only apply fertilizer. And big Hanchuan try anything twice in the late top dressing, according to Zhang, the collateral fully inflated are main factors to increase the yield of lotus root, and this depends on in the later stages of fertilizer adequate.
Heavy cost control - the price is not the first consideration
Big in the selection of fertilizer before considering the input and output ratio, prices are often not ranked in the first consideration of the factors. Baoji City, Shaanxi City, big brother, big brother, big brother species of 60 acres, he attaches great importance to control costs, he chose fertilizer has two principles, one can guarantee 6500 kg / acre yield, two is stable quality, low cost. "If the yield over 6500 pounds, overfulfilling portion of fertilizer input costs offset, I also want to choose."
Research found that retail investors are very sensitive to price, easy to select fat map. General retail in the later period of wheat will not add fertilizer, but due to wheat in filling root absorption capability of nutrient becomes weak, timely to foliar fertilization is wheat at grain filling stage the best fertilizer, especially potassium supplement for the transportation of nutrients have better effect. Jiangsu Yangzhou City wheat planting households sister Lee said, in order to protect the wheat yield late by foliar fertilizer supplement nutrient, the although the increase in the cost of fertilizer, but on the yield and quality of wheat in the late promotion effect. Relatively large, retail in the scientific selection of fertilizer, fertilizer, control costs based on weak.
