Field management of growing figs

The main results are as follows: (1) Intertillage weeding: the young garden should carry out intertillage weeding once in spring, summer and winter, and combine intertillage with soil cultivation to prevent freezing in winter. The adult garden is ploughed during dormancy and covered with grass in summer, which can not only inhibit the growth of weeds, but also prevent drought and preserve soil moisture. If there are still weeds, mowing is feasible, the grass will cover the rhizosphere, and appropriate crops can be selected for intercropping in winter. In cold climate areas in winter, we should pay attention to anti-freezing, such as Xinjiang every winter will branches pressed to one side or all around, covered with grass, and then buried soil, can be safe through the winter.

(2) fertilization: according to relevant reports, the adult garden needs about 10 kg of nitrogen, 8 kg of phosphorus and 8-10 kg of potassium per mu. No matter what kind of fertilizer, but should be stable compost, compost, human feces and urine, plant ash and other farm manure. The basal fertilizer should be applied in the dormant period, the total amount of nitrogen is 2max 3, the total amount of potassium is lmax 2, the amount of phosphorus can be fully applied, and the rest of nitrogen and potassium can be applied from June to July. The growth and extension of fig shoots and fruit harvest period are very long, so the fertilizer effect of nitrogen and potassium is prolonged accordingly, which can not be interrupted. In ordinary soil, if the application of lime 50 Mu 75 kg per mu, the effect will be better. It is best to apply fertilizer comprehensively in the adult garden, and topdressing can be irrigated with liquid fertilizer.

(3) Irrigation and drainage: when cultivated on the soil with heavy texture, the roots are mostly distributed in the upper layer of the surface, and they are vulnerable to drought when the climate is hot and dry. At this time, it should be watered in time to keep the soil moist. The fields without intercropping should be covered with grass in summer, which can not only reduce soil temperature, maintain soil moisture, protect fibrous roots distributed on the surface, but also increase soil organic matter and improve soil fertility. When cultivated in low-lying areas or when there is too much precipitation, it is easy to accumulate water in the field, so we should open good drainage ditches, lower the groundwater level and remove the stagnant water in time.

(4) pruning: in order to control the tree shape, the seed setting rate should be properly pruned during winter dormancy every year. The specific methods are as follows:

Pruning the main branches and secondary main branches of ①. In order to create a natural happy crown, the three main branches of the young trees are about 60 cm long and a cut bud is left outside its apex so that it continues to extend in the same direction. The lengthening branch should be moderately cut short in winter, and the remaining length is longer than the secondary main branch left under it, so that it is easy to maintain the subordinate relationship. The secondary main branch should not occur above the main branch. It's better to come from the side. It can also come from under it if necessary. When the shape of the tree is completed and the main branch has stopped lengthening, the branch of the secondary main branch leaves 2-3 buds short every year.
