Planting techniques of tree pineapple

Tree pineapple is what we usually call jackfruit. Tree pineapples generally like to grow in places with plenty of sunshine, high temperature and more rainfall, and the fruit is the heaviest fruit in the world. Its fruit has high medicinal value, and jackfruit is generally sold in supermarkets. Let's take a look at how it is planted.

Planting techniques of tree pineapple

1. Soil preparation: we should turn the orchard deeply one month in advance. The orchard that has been deeply turned over is beneficial to the root growth of young trees. If it catches up with the rainy days when planting, so much the better. Planting in rainy days is good for survival.

2. Opening holes: jackfruit's planting hole is 50 cm deep, the bottom is a square 40 cm wide, and the horizontal plane is a square 60 cm wide. The planting hole is in the shape of a ladder with a narrow bottom and a wide upper.

3. Base fertilizer: when planting, we should apply enough base fertilizer, we should prepare more farm organic fertilizer such as chicken manure, and prepare calcium superphosphate and other phosphate fertilizer. After opening the hole, first mix the two kinds of fertilizer together in proportion, applying 15-20 kg of organic fertilizer and 500 g of superphosphate per plant. After mixing, first apply a layer of bottom fertilizer, then return to a layer of inner soil, and then mix the soil and fertilizer evenly. Then apply the second layer of fertilizer, and then go back to the soil and mix well. When returning to the soil, build a colonization pile 10 centimeters above the ground.

4. Colonization: dig a small hole with a depth of 25 centimeters on the planting pile, and the other person slowly unties the seedling bag, puts it upright into the hole, straightens the seedling, then returns to the position flush with the stem of the rootstock, and finally compacts with both hands to complete the planting. It is better to plant 18 or 19 plants per mu. Finally, cover the planting hole with a layer of weeds.

Growth conditions of tree pineapple

Jackfruit does not care about the soil, but the sandy soil with deep topsoil is the best. If the soil is fertile, it grows very fast. Drainage should be good and sunshine should be adequate. Big trees have few whisker roots and are not resistant to transplantation. if transplanting is necessary, root cutting should be done first, branches and leaves should be trimmed before transplanting, especially in autumn and winter. Spring and summer is the peak growth period, topdressing once every 1-2 months, and fully replenish water, the big tree is very extensive. The sex is fond of high temperature and high humidity, and the suitable growth temperature is 22-23 ℃.

Fertilizer application of tree pineapple

1. Attack seedlings, strong plants and fat plants. In order to promote strong plants, adequate nutrients, high quality and high yield, fertilizers should be applied according to the following times and the amount of fertilizer applied per 15 hectares after planting. Fertilizer should be applied about 40 days after planting for the first time, and 5 kg of urea should be applied every 1x15 ha. For the second time, about 60 days after planting, 25 kg of phosphate fertilizer, 7.5 kg of potash fertilizer and 8.5 kg of urea were applied in the ditch. For the third time, 5 kg of urea was applied 80 days after planting. For the fourth time, 10 kg of urea, 20 kg of compound fertilizer and 7.5 kg of potash fertilizer were applied 90 days after planting. For the fifth time, 5kg of urea was applied 110 days after planting. For the sixth time, 5kg of urea was applied 120 days after planting.

2. Increase the fat of bud. In order to promote the rapid growth of plants and the growth of buds, about 10 days before budding, 15 hectares of urea and 22.5 kg of potassium chloride should be applied every day.

3. Attack fruit and promote budding fertilizer. In order to promote the rapid growth of young fruit and promote the emergence and growth of new buds, urea 3.5 kg per 15 ha was applied for the first time at Xiehua 1 / 2, and 3.5 kg urea and 10 kg potassium chloride were applied 20 days after the first fertilization.

4. Strong bud fertilizer. In order to promote the growth of small buds on the plant, and to provide high-quality seedlings for lower production, urea was applied every 15 hectares of 3.5 kg per hectare 10 days after fruit harvest. The effect of fertilization is better after rain.

5. Overwintering fat. Before entering winter, overwintering fertilizer should be increased to make the value plant grow healthily and increase the ability of cold resistance.

Main insect pests and control methods of tree pineapple

1. Fruit rot. Strengthen cultivation management, proper pruning in winter, topdressing organic fertilizer. Timely flower and fruit thinning, spray to control insect pests, harvest fruit gently handle, avoid damage; fruit ripening period can spray 1% Bordeaux liquid, or 50% Sukeling 500 times liquid. Or 58% Ruidu Manganese Zinc wettable powder 800-1000 times, sprayed once a day for 7-10 days.

2. Anthrax. Preventive measures should be taken on the basis of strengthening management and spraying protection at an appropriate time. After strengthening the management of fruit harvest, we should loosen the soil, increase the application of organic fertilizer, cut off the diseased branches and leaves and diseased fruit as far as possible, and spray protection during flowering and young fruit stage. The common medicines are: 50% carbendazim wettable powder 500-600 times, 40% carbendazim glue suspension 500 times, 50% carbendazim wettable powder 500 times and 75% chlorothalonil wettable powder 600-800 times.

3. Egyptian cotton scale. Pest Shaoliang can be wiped out manually when it occurs. Spray turpentine mixture 8-15 times.

Every step of planting jackfruit is very important, which is directly related to the later reproduction, so we should be a little more patient when cultivating. Only in this way can the high-yielding jackfruit be planted in the later stage. Often eat jackfruit for people suffering from thrombotic disease, has a very good adjuvant treatment effect, the nutritional value is very high.
