Soil testing, formula fertilization, seven-word song
The Party Central Committee and the State Council determine the subsidy counties for soil testing; the county's arable land tests again, and formula fertilization is the key. The crop needs more than ten kinds of fertilizers, all of which are sufficient for high yields; nutrient imbalances are prone to illness and the symptoms are different. Nitrogen deficiency inhibited the growth of the seedlings, the old leaves were yellowing and the new leaves were pale; the roots were fine and woody, and the flowering delay was easy to fall. Phosphorus-deficient plants had fewer tillers, and the new leaves were dark green and purple; the stems were red and purple roots were sparse, and the flowers were less grainy. The potassium-deficient plants are short-growthed, and the old leaves have sharp edges and yellow wilts; the stalks are weak and easy to lodging, and do not resist disease to resist cold. Calcium-deficient old plants are in decline, hook-shaped adhesions of young leaves, root tip rot, and wilting of umbilical rot in eggplant. Boron-pore top leaf shrinkage, axillary bud clustered buds; root easy to die stems easily cracked, flower flowering not seen fruit. Zinc deficiency short and short stature, thinning new yellow and white flesh; corn white mosaic disease, peach pear leaflets or clusters. The top of the iron deficiency is green, and the fruit trees are the most obvious; young veins are yellowed first and the skin is hard to correct. Insufficient relies on fertilizing, supplementing and supplementing, and minimizing quasi-adjustment; organic and inorganic combination, and scientific compatibility. Fertilizer slag and stalks are used for irrigating crops. Farming land for crops should be given priority. The variety and variety of chemical fertilizers have their advantages and disadvantages; nutrients are suitable for quick results and every crop is liked. Blind fertilization is a disadvantage, and it wastes precious resources indiscriminately; plagued with pests and diseases, all can reduce grain. Nitrogen, phosphorus and potassium fertilizers are three elements: copper, iron, zinc, boron, manganese and molybdenum; single fertilization is difficult to meet, and the soil testing formula is not blind. Measurement and distribution of production for one-stop, the combination of technology is very popular; lack of fill into the package, the formula fertilizer nutrition. A local technician is employed to test the soil and fertilizer stations. Experts formulate the formula and the company produces it for production. Provincial fertilizer factory, the township has a dealership; fertilizer formula is fine and accurate, batch sampling and strict control. Woori fertilizer Xiayu production, rich red nutrients; assured fertilizer locomotive, four fertilizers for your choice. The distribution channel is very simple, direct sales to households spend less money; rural areas have a fat supply point, see the signs and then pay. Fertilizer must be deepened, reaching a depth of two and a half inches; do not throw Dishi, waste fertilizer and pollution. If you want to buy safe and fat, go to the village instructor; fertilization there is also difficult, telephone consultation soil fertilizer station. Calling agricultural technicians one by one, experts, etc. are on the phone; from then on to get rich bridge, Xiaokang on the road forward.
