Planting techniques of toad grape

A mangy grape is a small fruit that is red when ripe and has more seeds inside. This part is inedible. The appearance of the grape has many uneven small pieces, it does not look very good, but its role and effect is very many, and now more and more consumers love it.

Cultivation techniques of mangy grape

1. Field preparation. After sun-drying and freeze-thawing, the soil blocks are broken by mechanical rotary tillage, and the longitudinal section of the ridge is trapezoidal, the bottom width is about 1.6m, the upper bottom width is 0.8m, and the ditch width is 0.8m. In the center of the ridge, 2000kg of high-quality farm manure, 150kg of vegetable cake and 25kg of compound fertilizer potassium sulfate are applied as base fertilizer. Frame can be erected before planting, can also be carried out after planting. Insert a bamboo stick next to each plant and form a "1" shape. Connect each row with bamboo sticks and form a "well" shape at the top. It can be denser, which is conducive to vine climbing. However, ventilation should be considered, and at the same time, let the mango fruit hang down. The height of the frame can be operated freely by people in the furrow, and the distance from the furrow to the top of the frame is about 1.8m.

2. Sowing seedlings. Nurturing seedlings in small arch shed at the end of March and early April. The seeds are soaked in hot water at 50℃ for 30 minutes, then soaked in warm water at 25-30℃ for 5 hours, and then germinated at about 30℃ under humid conditions for about 3 days. After the broken shell buds are exposed, insert them into nutrient bowls, one seed per bowl, cover a small amount of soil, and cultivate some fine soil after emergence. Seedbed north-south direction, early anti-cold, late anti-high temperature burns, seedling temperature and humidity is too large, should be timely ventilation cooling humidity, seedling generally do not need fertilization. After 20 days or so, there are 2-3 true leaves can be transplanted, generally before rain, cloudy day transplanting. It is generally planted with 400-500 plants per mu.

Field Management of Grapes

1. Water and fertilizer management. When planting, irrigate enough root-fixing water, spray 0.2-0.3% potassium dihydrogen phosphate on leaves one week after planting. The mangy grape bears drought, but likes the moist soil environment, meets the drought to be able to irrigate runs the horse water. Generally, a small amount of results began to be produced around June 20, and a large number of products began to be listed around July 10. At this time, 25kg compound fertilizer was applied per mu, and some compound fertilizer was applied according to the growth situation at the end of August.

2. Field weeding. 7 days before planting, use the herbicide Roundup once. Later, depending on the growth of weeds, use the gramineous herbicide Quinclofop-p-g.

Plant adjustment method of mango grape

Each leaf of the main vine can grow a lateral vine, so all the lateral vines below 1m are picked, and 3-4 lateral vines are left with the main vine. The growth of mangy grape plants has such a characteristic: before the vine is put on the shelf, it needs to be tied up continuously until the vine climbs to the top of the shelf. The climate is dry and the vine grows slowly. After rain, the plant grows very fast. If the vine grows very well in the fruiting period, some lateral vines can be removed appropriately to inhibit its growth, promote reproductive growth and improve yield.

Pest control method of mangy grape

1. Catastrophe. Control measures: ① Seedbed disinfection: 70% quintozene and 50% thiram were used to disinfect soil in planting ditch before planting. (2) Chemical control: 72.2% propamocarb hydrochloride 750 times or 58% metalaxyl·mancozeb or 75% chlorothalonil 600 times or 32% metalaxyl·hymexyl 300 times can be sprayed on the seedling base.

2. Anthrax. Control measures: ① Select disease-resistant varieties and disinfect seeds. (2) rotation between seriously ill land and non-melon vegetables.③ Avoid partial or excessive application of nitrogen fertilizer, increase phosphorus, potassium fertilizer and medium and trace element fertilizer, control irrigation properly at the same time, and remove accumulated water after rain.④ Remove diseased leaves, diseased branches and diseased melons in time, and keep the field ventilated and transparent. (5) Chemical control: spray 25% prochloraz 1500 times before onset, spray 10% difenoconazole 1500 times or 32.5% azoxystrobin and difenoconazole when onset.

3. Brown spot disease. Control measures: ① select high terrain, good drainage plot planting.② Set up shed, prune branches and pick leaves in time to improve ventilation and light transmission conditions in the field.③ Base fertilizer is mainly organic fertilizer, top fertilizer is combined with nitrogen, phosphorus and potassium, and foliar fertilizer for melon and vegetable is sprayed.④ Irrigate water in time, remove accumulated water in the field after rain, and pay attention to controlling humidity in the field. (5) rotation should be carried out in seriously ill areas. 6. Chemical control is the same as anthrax.

The planting technique of mangy grape is also simple, it is necessary to select the right time, and then the seeds are germinated, so that they can be planted. The ability to divide plants is very strong, so it usually has a high yield. Choosing to grow mangy grapes is a very good way to increase economic income.
