Clove cultivation techniques
Planting land should be selected for calm wind environment with low groundwater level (below 3cm), deep soil, loose fertile loam soil or sandy loam soil. Before opening the planting hole, fertilize, red soil or yellow soil, apply base fertilizer in the planting hole. , And in the process of growing organic fertilizer applied year after year to improve the soil. The nursery should choose a flat terrain, convenient irrigation, sandy soil or loam soil with loose soil, plow 20-25cm before sowing, 1000-2000kg humus in Mushi, mix well with topsoil, fine level and make it 1.3m Wide squats or flats, shaded sheds, 30% to 40% transmittance, and good drainage ditch around to facilitate drainage.
Second, field management
a) Intercropping shading plants 1-3 years of saplings intolerant of exposure, need to shade, maintain 50% -60% shade.
(b) It is particularly important that the ground cover is in areas where dryness and wetness are evident. Can be planted with green manure to reduce the evaporation of soil moisture, cool and moisturize in summer, prevent rain erosion, and keep warm in the winter.
(C) fertilization, soil cultivation should be applied in spring 2-3 months. The strain applies 15-20kg of animal manure water, 25-30 parts of ammonium sulfate, 50-100g of superphosphate, 100-150g of potassium chloride or potassium sulphate, 10-15kg of mixed manure, and ditching. If the root system is exposed, earth should be properly soiled.
(4) Trim to maintain the shape of the tree, increase ventilation, light transmission, can be cut from the main branch of the cloves from the ground below 7Ocm-1m, weak branches, disease branches, too dense branches should also be cut together.
(5) Windproof cloves The aboveground twigs and leaves are luxuriant, the canopy is large, and the twigs are crisp, while the root groups are shallow and slender, and the support is weak. In areas with frequent typhoons, windbreak work should be done before the typhoon comes. Ropes or bamboo can be used to fix the plants.
IV. Pest Control
(I) Leaf damage caused by brown spot disease occurs in hot and rainy seasons, and lesions on the affected leaves appear brown, round, and gray with white perforations. Control methods: At the beginning of the disease, 1:1:100 Bordeaux fluid is used for prevention and treatment.
(2) Soot damages the tender stems and leaves, and a layer of soot-like material is covered by the affected parts, which affects photosynthesis, and then causes the plants to wilt, mostly caused by the secretions of aphids and scale insects. Prevention and control methods, pest control and treatment, use 40% dimethoate cream to control aphids, use 0.2-0.3 Baume degree lime sulfur agent to control scale insects; strengthen management, proper trimming, increase ventilation and light transmission, adjust under forest microclimate, enhance tree potential Reduce the incidence.
Sunson Group supplys Phytase, Cellulase, Xylanase, Mannanase, Protease, Alpha Amylase, Glucoamylase, Beta glucanase, Complex Enzymes for poultry, swine and ruminants. As an animal feed additive used in poultry and swine, Sunson Phytase can enhance the nutritive value by liberation of inorganic phosphate from phytic acid (myo-inositol hexakisphosphate) , thereby, reduce phosphorus pollution to the environment. Alpha Galactosidase can reduce the viscosity of intestinal contents, thus increasing the hydrolysis of nutrients to promote their digestion and absorption.
Benefits:
Promote the digestion of livestock
Reduce costs of feed
Increase the yield of livestock products
