Maize cultivation fertilizer management and pest control
Mashan medicine is also known as yam, as well as yam and other aliases. It grows in the mountainous areas in the shade, and can be used as medicine. The taste is very good. Many areas have artificial large-scale planting. Let's take a closer look at the value and growth management of this crop.
Mashan medicinal origin
Mashan yam is mainly grown on hillsides and valleys, and artificially cultivated. Mainly distributed in Northeast China, Hebei, Shandong, Henan, Shanxi, Jiangsu, Zhejiang (450-1000 meters), Jiangxi, Fujian, Taiwan, Hubei, Hunan, northwestern Guangxi, Guizhou, northern Yunnan, Sichuan (700-500 meters), Eastern Gansu (950-1100 meters), southwestern Shaanxi (350-1500 meters) and other places.
Main value of yam
Applicable to physical weakness, mental fatigue, loss of appetite, indigestion, chronic diarrhea, fatigue, cough, nocturnal emission, night sweats, diabetes and nocturia. Yam is rich in nutrients and contains various substances such as protein, arginine, vitamins, sugars, minerals, mucus, starch, etc. Among them, amylase decomposes starch, so it does not lag. Mashan medicine can be used as medicine, it is a tonic medicine, it enters the lungs and the spleen and stomach. Therefore, it has the effect of clearing the lungs, moistening the lungs and tonifying the spleen.
Mashan yin growth habit
Hi light, not cold-resistant, should be grown in well-drained, loose and fertile soil, avoid chlorine, avoid water. The underground yam stem is cylindrical, deformed due to different growth geology and farmyard manure, and the meat is thick.
Mashan Fertilization Management
Mashan medicine completely transports nutrients by itself, until after mid-June, and at this time the fertilizer effect of fertilizer has been lost. The experiment found that the fertilizer did not make the base fertilizer, but changed to the topdressing, which was chased three times in late June, late July and mid-August, respectively, compared with the bottom fertilizer and the two top dressing modes in mid-July and mid-August. The yield of only top dressing is high. Therefore, the application of organic fertilizer as a base fertilizer in fertilization can be applied once and the fertilizer can be applied.
Base fertilizer: 6 bags of billion bacteria + 2 bags of calcium, calcium and magnesium / mu.
Top dressing: (water soluble fertilizer)
1. (late June) high activity bacterial kinase + milk enzyme.
2, (late July) high activity bacterial kinase + water soluble fertilizer 10-20-20.
3, (in mid-August) high activity bacterial kinase + high potassium phytonin.
For the root rot-prone area, the following formula was used for treatment: Pu Dejin one barrel + flusilazole 300g + carbendazim 300g + high-activity bacterial kinase 10kg water 600gk was applied in early July.
Mashan pest control
1. Pest control
In the seedlings and growing season, using 50% phoxim emulsifiable concentrate 1000 times solution, 80% dichlorvos 1,000 times solution, 2.5% kungfu 3000 times solution, etc., spraying on the surface of the plant and the ground can prevent cockroaches, tigers, and twenty-eight Pests such as ladybugs and green blinds.
2, disease prevention
For brown spot, anthracnose, and spot blotch, the key to prevention and treatment is post-emergence spray protection. The first dose must be seized after the yam sputum is put on the shelf, before the onset of the critical period, such as the first drug late, after the onset of medication, the disease control effect will be significantly reduced, the medication interval should be flexible, continuous drought can be The interval is about 15 days, and it can be shortened to 5 to 7 days in case of rainy weather.
Before the onset and in the early stage of yam growth, 70% Antaisheng wettable powder 700-800 times, 50% Fumei double wettable powder 500-600 times, 80% mancozeb wettable powder 500 times liquid spray. After the onset, it is advisable to control the disease by alternately spraying with 1.5% thiazolone water agent 1000 times, 25% ampicillin suspension agent 1500 times, and 25% amide amide wettable powder 800 times. Because the leaves of the yam are smooth, it is better to add the adhesive when applying.
The above is about the introduction of yam, no matter what crops are planted, good management and disease control can effectively increase the yield of its varieties. The above-mentioned contents hope to help the yam growers.
