Soil management is mainly loosening and weeding, good soil management on wolfberry high quality and high yield, efficient cultivation will play a half-hearted effect. The ideal method of loosening and weeding is to use a small rotary tiller for tilling, the benefits of mechanical tilling is high efficiency, labor saving. The key seasons for tillage are late March in early spring, early May in early summer, and mid to late August and early September in early fall. The purpose and effect of each tillage is different.
1、Tillage in late March
This not only raises the soil temperature, loosens the soil, conserves moisture and reduces water evaporation, but also turns down all the weeds that grow in early spring.
2、Tillage in early May
The main purpose of this period is to weed control. At the same time to improve the aeration conditions, reduce water evaporation, coordinate the root system water, fertilizer, air and heat relationship. This can promote the slow absorption of nutrients. Ensure that the wolfberry spring branch growth strong, improve the flowering and fruiting rate of wolfberry.
3、Mid to late August tillage
This period, we can loosen the soil, improve the physical structure of the soil, enhance soil aeration. This can promote the root system of Chinese wolfberry in the second growth peak good growth, for the above-ground Chinese wolfberry canopy to transport more nutrients.
4、Autumn garden turning
In early September, we deep-turned the whole garden to dry the soil, while eradicating the root tiller seedlings. In addition, weed plots, after each watering to tillage once. Weeds such as rushes, which are difficult to eradicate completely by tilling, are treated with herbicides. For soil caking, saline serious plots, each time after watering to loosen the soil.
B、The fertilization of wolfberry
Goji berry is a very fertilizer-loving tree species. We want to make the wolfberry garden early fruit yield, we must give full play to the fertilizer in the wolfberry young age during the expansion of the crown and increase yield role. Fertilization needs us to focus on the following three links.
1、Fertilization before planting
Chinese wolfberry seedlings before planting, in the hole to apply organic fertilizer 2 ~ 3kg, plus compound fertilizer 100g. currently, the market with more compound fertilizer, is the Nagric company produced.
When the planting of Chinese wolfberry seedlings, after the seedlings become viable, to start chasing fertilizer. Generally from the third irrigation before the first chase fertilizer, has planted the wolfberry garden, to be in late April before the first irrigation to start chasing fertilizer. This chase fertilizer to phosphorus fertilizer, the purpose is to let the root system fast growth. This is also conducive to early crown development and more various types of branches.
The second fertilization was carried out in early June. With nitrogen, phosphorus and potassium compound fertilizer. The purpose is to promote the growth of branches of wolfberry, more flowers, more fruit. At the same time, also promote strong branches hair more. We through short pruning after pruning, fast hair, more secondary branches.
The third fertilization was done in late July. We put nitrogen, phosphorus fertilizer mix, or apply compound fertilizer. The purpose is to ensure the nutrition needed for the maturity of the wolfberry fruit.
3、The amount of fertilization
The amount of fertilizer is 0.25kg per plant for young Lycium barbarum trees and 0.5kg per plant for mature Lycium barbarum trees. the location of the fertilizer can be staggered before and after. The method of fertilization is: along the outer edge of the Chinese wolfberry crown open 10cm~15cm deep, 30cm~40cm long trench. Then, we spread the fertilizer evenly. Finally cover soil irrigation.
4、Autumn fertilization base
In October, this fertilization is the annual foundation work. This fertilizer application requires that it is best applied before mid-October. This will facilitate further recovery and growth of the root system in mid to late October. This fertilizer application requires a deep application. Method: We dig two symmetrical pits 50cm long, 30cm wide and 45cm deep along the outer edge of the Chinese wolfberry crown. Then, deep application of farmyard manure, 1000kg~1500kg per mu, 3kg~5kg per plant. finally, mix with soil and seal the pit.
Wolfberry year planting to immediately after irrigation. Later we can according to the soil moisture, 7 ~ 10 days and then irrigate once. Wolfberry completely alive after the irrigation of the third water. And combined with irrigation to start the first chase fertilizer. Later irrigation, we can combine with fertilization at the same time. Has built the wolfberry garden, the first irrigation time in late April. The number of irrigation throughout the year, generally 6 to 8 times. The number of irrigation, mainly according to the soil drainage situation to decide. Poor water retention on more irrigation, poor drainage on less irrigation.
In short, Chinese wolfberry planting year irrigation, without affecting the normal growth of Chinese wolfberry premise, can less irrigation, as little as possible. Such management is conducive to the root system of Chinese wolfberry to deep growth, for later deep roots and leaves to lay a good foundation.
We want to achieve high quality and high yield of Chinese wolfberry, it is necessary to carry out plastic pruning. Pruning is divided into spring pruning, summer pruning, winter pruning. 1 to 4 years of age of the first fruit, summer pruning is the key.
Winter pruning, generally in the Chinese wolfberry after the fall of leaves to spring buds sprouting before. We generally prune in February to March. Mainly cut out the root sprouting tiller of the long branches, thinning out the Chinese wolfberry tree chamber affect the crown extension, blocking light and tree balance of large and medium-sized strong branches and long branches. As well as not fruit or fruit less old and weak disease residual branches. This can make the wolfberry crown branches up and down smoothly.
Spring pruning after budding to before the exhibition of leaves, mainly to make up for the winter pruning deficiencies, cut off the Chinese wolfberry branch trunk tip and pinprick.
Summer pruning, also called growing season pruning, spans the spring, summer and fall seasons. Among them, late April to the end of June is a critical period of summer pruning, generally 8 to 10 days apart. Our first task is to cut out the long branches to reduce nutrient consumption. Next, we cultivate tree shape and fruiting branch groups by short-cutting and heart picking. Sourcing from:https://nagric.com/fertilization-techniques-for-wolfberry/
