High-yielding planting techniques of aconite

Aconite, also known as Aconitum, etc., is a plant of the genus Aconitum of Ranunculaceae, mainly produced in Sichuan, Hubei, Hunan and other places. it has extremely high cultivation value, like warm, moist and sunny environment, cold tolerance, and avoid repeated crops. it is better to cultivate in the soil with deep and fertile soil layer, loose soil, good drainage and rich humus. Let's take a look at the high-yield planting techniques of Fuzi.

Land selection and land preparation of Fuzi

The aconite planting land should select deep, loose and fertile mountainous areas. starting from heavy snow, in late October, stable manure or compost per mu should be applied as base fertilizer, 1.2 meters wide and 1 meter wide. 50 kg calcium superphosphate and 50 kg vegetable cake should be mixed and sprinkled into the border surface, stirring evenly in preparation for subplanting.

Reproductive techniques of aconite

1. Monkshood propagates with tuber root. The root tuber can be divided into three levels according to its size. The first one weighs 2 kg per 100 tuber roots, the second weighs 0.75 kilograms, the second weighs 0.25 kilograms, and the third weighs 0.5 kilograms. The first and third stages are mostly used as aconite roots, and the second tuber roots are used as aconite roots, 11000 to 12,000 roots per mu, 130 to 150 kilograms per mu, usually with black scar on the root bark. Water rotatory disease and tuberous roots with wounds, diseases and insect pests should not be planted.

2. After the root of aconite seed is dug out, it is spread out (about 6 cm thick) in a cool leeward place to dry for 15 days, so that the moisture in the cortex is slightly dry and can be planted. In the first and middle of November, the seedlings were planted in the pit with row spacing of 15x18 cm and nest depth of 12 cm in order. The covered soil was 9 cm thick and the back of the adult fish was shaped to facilitate drainage. When planting, one more root can be planted every 10 plants, in order to replenish the seedlings and ensure high yield.

Field Management of Fuzi

1. Ploughing and replenishing seedlings: during the cultivation of aconite, weeding was shallow once before and after the middle of November, so as to keep the field free of weeds. After the seedlings came out in the early spring of the second year, the seedlings were replenished in time, and the healthy seedlings were replanted with soil, compacted and watered to facilitate survival.

2. Topdressing to cultivate soil: Fuzi is generally topdressing for 3 times. When 5-6 leaves appeared in early February, 3000-3500 kg of water and fertilizer per mu were used to dig small trenches between rows and irrigate them once. For the second time, after repairing the root of the disease in May, 3000kg of human feces and urine or 250kg of cruller fertilizer was applied, and one hole was dug out among the three plants to cover the soil. The third time was carried out in early August, using 1000 kg of human and animal dung water, 10 kg of urea and 1000 kg of water per mu. The soil is cultivated at the same time of topdressing, which is 6cm to 15cm thick and shaped into the back of a fish.

3. Pruning and root trimming: when the height of aconite seedlings is 30cm to 36cm. Pick the high tip for the first time, pick the tip of the second type of seedling after 7 days, and pick the tip of the third type of seedling after 7 days. After picking off the tip, the bowels grow fast and should be removed in time. Trim the root once before Grain Rain and after the Beginning of Summer in early April: gently open the root soil, evenly retain 2 or 3 strong new aconite, cut off all the rest, and be careful not to hurt the root and stem.

4. Harvest and processing: aconite is generally harvested in late July. Dig out the whole plant with two-toothed rake, shake off the sediment, take off the aconite, remove the fibrous root into a mud aconite, which needs to be processed immediately. At the same time, the mother root was cut off and dried into aconitum.

Disease and insect pest control of aconite

1. White silk disease: it often occurs in the summer high temperature and rainy season, causing damage to the root and stem of aconite. Choose disease-free aconitum as seed, rotation, mix well with 2 kg of pentachloronitrobenzene powder and 50 kg of dry fine soil per mu, apply it around the rhizome and cover the soil, deeply bury the diseased plant and soil at the initial stage of the disease, and irrigate the healthy plants near the diseased plant with 1000 times of lime or 50% carbendazim wettable powder.

2. Downy mildew: downy mildew usually occurs from March to May, causing damage to leaves. Pull out the diseased seedlings in time and spray them with Bordeaux solution of 1 Drexel 200 or 800 times of 65% Dysenamine wettable powder.

3. Root rot: root rot usually occurs from April to July, causing damage to the roots. Do not damage the rhizome when pruning, but apply more alkaline fertilizer and irrigate with 1000 times of carbendazim wettable powder.

4. Red aphids: red aphids usually start in late March or early April and flourish from May to June, harming the tender stems at the top of the plant. Prevention and control method: 40% dimethoate EC 800-1500 times liquid spray.
