The latest course of High-yield cultivation techniques of March Plum

March plums are a precocious variety of plums. Generally speaking, in March, these plums will mature and can be harvested. Generally speaking, March plums are sour and crisp and delicious. Fresh plums that are eaten after pickling can also be made into preserved fruit. So now March plums occupy a unique market in plum cultivation and sale. So many people began to grow March plums, which were first listed on the market. Well, many people are also very concerned about how to grow March plums to achieve high yield. I will introduce them to you today.

I. Seedling and planting

Plum trees can be propagated in several ways, but in actual production, rootstocks are generally sown and then grafted. Because rootstocks are generally resistant to cold, drought and waterlogging, wide adaptability and strong resistance, and scions often have excellent variety characteristics, so choose grafting to raise seedlings. Generally sow rootstock first, wait for rootstock to grow to about 20 cm, you can prepare scion, to carry out grafting, grafting generally uses the most common skin grafting method. Hairy cherries can be used as rootstocks. Grafting is usually carried out in spring and is easy to survive. At the time of planting, the best line spacing is about 3 meters, with a spacing of 2.5 meters.

II. Selecting gardens

Plum gardens generally choose the soil with better humidity and temperature conditions, so it is generally best on the hillside with slightly higher terrain. The soil had better be deep, flat, rock-free, well-drained structural soil, not planted in saline-alkali land, gravel land, low-lying land. With regard to light, it does not have to be sunny, it is not strict with the light.

Third, fertilizer and water

Before planting in the first year, farm manure should be used as base fertilizer during soil preparation, generally about 2000 jin per mu of base fertilizer. This is the first year that trees must apply more base fertilizer, and after that, it will be about 1500 jin per mu. The whole garden was irrigated once a week before the application of base fertilizer, so as not to harm the roots when planting. Then topdressing, basically no topdressing less topdressing in the first year, and more topdressing in the second year, mainly in the flowering and fruiting period, generally topdressing about 500 jin of farm manure at a time in the flowering period, and topdressing many times in the fruiting period, about 100 jin at a time, irrigating each time a week before topdressing, and applying basal fertilizer to fruit harvest.

IV. Shaping and pruning

Generally, after planting, the stem is set 70 to 80 centimeters off the ground, all the buds on the trunk are removed, and then three or four healthy branches are selected as side branches, and then the other branches are removed. After that, you can continue to keep branches, leaving five to six branches on each side branch, leaving branches for three to four times, and the crown is ready for type. After a branch grows to more than 1.5 meters, it is necessary to pick the heart. Then cut off the disease and insect branches, dense branches, withered branches and overgrown branches every year, and renew and rejuvenate at the same time.

The planting of plums in March is the same as that of other plums, but the maturity is different. Therefore, we need to make different management measures, and the things we should pay attention to will also change. I hope you can find a corresponding good way to plant and achieve the goal of high yield.
