The latest course of field management techniques and methods of Ziziphus jujuba

Calligonum alias longevity fruit, its fruit pulp sweet slightly sweet astringent, can be eaten raw, wine, boiled sugar, high edible value, but also has a high medicinal value. Do you know how to manage the field? Let's get to know each other together with Xiaobian.

1. Fertilization

Calligonum is fond of fertilizer. On the basis of applying sufficient base fertilizer, topdressing is needed twice a year. The first time is carried out in the first ten days of May, and the second time is carried out in the middle and late ten days of July. Generally, each plant is applied with decomposed farm manure 5kg and calcium superphosphate 100g. After mixing them evenly, they are applied in furrows. Fertilization should be applied once after fruit picking, generally before freezing, mainly with decomposed farm manure, covering the root system 1-2 cm deep or covering a layer of litter and pressing a layer of soil, which can not only keep warm and keep moisture, but also avoid bud damage, which is beneficial to seedling emergence and yield of the next year.

2. Intertillage and weeding

Cultivate and weed 3-4 times a year to promote the growth and development of plant roots. Pay attention to the depth of cultivation to avoid damaging roots. Generally, the bed should be shallow and the middle should be slightly deep. The root system should be shallowly hoed. In order not to damage roots, weeding should be frequent. If it is a small area cultivation, manual weeding is recommended. Herbicides are recommended for large area cultivation. However, attention should be paid to the concentration and spraying method when using, so as not to affect the plants.

3. Drought prevention and drainage

Calligonum is a fibrous root crop. The root system is mostly distributed in the 15 cm soil layer, so it is afraid of drought and waterlogging. Drought often occurs in May and June in Northeast China. In case of drought, it should be watered in time to keep the soil moist and promote plant growth. And in July-August when it is rainy season, it is necessary to dig a good drainage ditch in advance, timely remove water between the garden, reduce humidity, reduce the occurrence of roots and prevent pests.

4. Qingyuan

If there is no natural forest shade on the low ground, remove the mulch after emergence and immediately erect an awning covered with wormwood, straw curtains or nylon nets. Remove shade in September, wait for bitter taste on the ground, clean up the garden in time, pick up dead leaves and other sundries outside the garden and burn them, and spray chemicals to control diseases and insect pests.
