The third part: foliar fertilizer spraying:add 25 ml of wofengsu + 0.2% urea every 30 jin of water, spray twice, every 7 days.
the fourth part: soil conditioning:
increase the amount of biological fertilizer every 5-7 days, supplement beneficial bacteria, improve soil structure

Durian in Guangxi is so cheap that it is likely to be smuggled in. We should pay attention to buy "imported Durian" and pay attention to it; The safety and health of rian imported through illegal channels can not be guaranteed

with normal fruit development and no pests and diseases was selected for cleaning. Then the water was cleaned with water and then sprouted on the sand bed for germination. The sand bed covered 1~2 centimeters of fine sand, covering 1 layers of straw, and sprinkling 1~2 times a day, which sprout and germinate after about 1 weeks. When the seedlings grow 1~2 times, they can be divided into bed transplants. P>
jackfruit seedlings can grow to more than 1 cm and bud grafting. One year old and sunny branches should be selected as scions for good varieties. Scions should be kept moist, and it is better to be grafted as soon as they are harvested. Budding can be done all year round in Hainan, but the survival rate of budding is higher in rainy season and tree growing season from April to October. At this time, rootstocks and Scions are easy to peel and survive after grafting
jackfruit can be planted all the year round, but planting in spring (3~4 months) and autumn planting (9~11 months) is best. When planting, the soil in the planting hole should be fine, and the root system of the seedlings should be straightened out and straightened, and then layered into the fine soil. Immediately after planting, sufficient root setting water was poured, and the tree tray was covered with plastic film
environment: jackfruit grows well in areas with sufficient moisture and annual rainfall above 1200mm, and requires adequate sunshine. p>
temperature: annual average temperature ≥ 22 ℃, coldest month average temperature ≥ 13 ℃, absolute minimum temperature & gt; It can blossom and fruit normally at 0 ℃
mature: the grafted jackfruit usually begins to bear fruit in 5 years after planting, and the seedling can only be fruiting after 8 to 10 years. p>
extended data:
planting technology
in the annual average temperature ≥ 22 ℃, the coldest month average temperature ≥ 13 ℃, absolute minimum temperature & gt; It can blossom and fruit normally at 0 ℃. As a commercial cultivation, it should be developed in the place with the lowest monthly temperature and higher temperature. Jackfruit has sufficient moisture and annual rainfall in areas above 1200mm. Jackfruit requires adequate sunshine, but it is also very tolerant to shade. Seedlings are more resistant to intense sunlight, so they can be interplanted with lychee, longan, yellow skin, banana and plantain. Jackfruit can adapt to the growth of most soils, but it is best in fertile, moist and deep soil. p>
reclamation, digging holes and applying base fertilizer on flat land or in 5 ° The following gentle slope land is ploughed deeply by machine and then leveled. In the hilly land, the contour line should be used to open the circular mountain or terraced fields with a width of 1.5-2.5m, and the terraced fields should be inclined inward to facilitate water conservation. In Hainan, jackfruit is generally calibrated according to row spacing 5-6m and row spacing 6-7m, and 225-330 plants /hm² are planted. p>
dig 0.8-1.0 m long, wide and deep holes. The topsoil and subsoil shall be stacked separately ring excavation. When returning soil 1-2 months before planting, the top soil should be applied to the lowest layer first, then weeds should be put, the branches and leaves should be mixed with 0.5kg lime, and then returning to the first layer of surface soil, 50 kg pond mud, 50 kg livestock manure and 0.5kg phosphate fertilizer should be put (50-100g bacterial fertilizer should be put in the planting hole where conditions permit, the effect is better), and then one layer of surface soil should be covered, and the filling height should be 20cm above the ground. In this way, after 15-20 days or so, the soil pan sinks, planting can start
The planting time in Hainan could be carried out throughout the year, but spring was the best. Strong seedlings with 25-26cm height should be selected for planting. When transplanting the seedlings, it is necessary to avoid damaging the roots, put the seedlings into the planting hole, then untie the plastic bag of the bandage, fill the soil mass with fine soil, and then fill the soil around. Cover the surface of tree pocket with grass to keep moisture, shade properly, and drench with root setting water
