High-yielding cultivation techniques of March Plum

March plum is an early-maturing variety of plum. Generally, this plum will mature in March and can be harvested. Generally, March plum is sour and crispy and delicious. Fresh plum can also be made into preserved fruit after pickling. Therefore, March plum now occupies a unique market in plum planting and sales. So many people started growing this first March plum. Well, many people are also very concerned about how to obtain high yields by planting March plums. Today, I will introduce them to everyone.

I. Seedling planting

Plum trees can be propagated using several methods, but in practice, the rootstock is generally seeded and then grafted. Because rootstocks are generally cold, drought and waterlogging resistant, adaptable and resistant, and scions often have excellent variety characteristics, so grafting seedlings are selected. Generally, the rootstock is sown first, and when the rootstock grows to about 20 cm, the scion can be prepared for grafting. Grafting generally adopts the most common skin grafting method. Cherry can be used as rootstock. Grafting usually takes place in spring and is easy to survive. The best row spacing for planting is about 3 meters and the spacing is 2.5 meters.

II. Garden Selection

Plums are grown in plots that generally choose soil with better humidity and temperature conditions, so generally higher slopes are best. The soil is preferably deep, flat, rock-free, well-drained structured soil, not planted in saline-alkali land, gravel land, low-lying land. Regarding illumination, it does not have to be sunny, it is not strict with illumination requirements.

III. Fertilizer water

Base fertilizer, in the first year before planting, soil preparation to apply farm manure as base fertilizer, generally about 2000 jin per mu base fertilizer, this is the first year trees must apply more, after the base fertilizer, about 1500 jin per mu. Irrigation the whole garden once a week before base fertilizer application, in order not to damage the roots when planting. Then topdressing, the first year basically no topdressing less topdressing, the second year can be more topdressing, mainly in the flowering period, the fruiting period topdressing, topdressing generally flowering period a topdressing of about 500 jin farm manure, fruiting period topdressing many times, a 100 jin or so, each time in topdressing a week before irrigation, there is fruit picking and base fertilizer.

IV. Shaping and pruning

Generally, after planting, 70 to 80 cm from the ground, start to stem, remove all the buds on the trunk, then select three to four healthy branches as lateral branches, and then remove other branches. After that, you can continue to leave branches, leaving five to six branches per lateral branch, so leaving branches three to four times, and the crown is waiting for shape. A branch left to grow to more than 1.5 meters after the need to pick the heart. Then after shaping, every year to cut off pests branches, dense branches, dead branches, excessive long branches, at the same time update rejuvenation can be.

The planting of March plums is different from other plums, but due to different maturity periods. Therefore, we need to make different management measures, and the matters to be paid attention to will also change. I hope you can find a good way to grow it and achieve high yield.
