Daxie County, Shaanxi Province is superior in light and heat conditions and has a large temperature difference between day and night. It is the best place for production of jujube in China. As the young jujube gardens (below the age of 3 years) have a small tree, the spacing between the rows is large, resulting in a waste of light and heat resources. In order to make full use of light, heat, and land resources to increase profits, high-quality cabbage varieties can be selected between young jujube orchards in mid-to-late February. In order to provide a good market, 15 to 20 days before the planting of spring cabbage, the backs of the fields can be removed and deep-turned.耙 耙 耙 耙 , , , , , , , , , , , , , , , , , 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金 金. According to test statistics, the intercropping technique can increase the economic benefit of 667m2 (1 mu) of winter jujube gardens from 2000 to 4,000 yuan.
Take the 667 m2 Dongzao Garden in Dayi County as an example to introduce the four main techniques for Intercropping Spring Cabbage:
1. Intercropping Spring Cabbage to Cultivate Strong Seedlings: The appropriate sowing date for spring cabbage is from late December to mid-January of the following year, and most of them use solar greenhouse nursery or improved Yangshuo nursery. About 667 m2 seed amount is about 50g, take dry seed live. Seedlings pods were first poured into foot water to spread cabbage seeds homogeneously, covered with sieved medicinal soils after sowing, and prevented seedlings from cracking.
2, intercropping spring cabbage seedling management techniques: before emergence, greenhouse or Yangshuo temperature should be maintained at 15 ~ 25 °C, general seeding after 5d can be Qimiao, then pay attention to timely and gradually release air, so that the temperature is maintained at 10 ~ 20°C. If the seedlings are too dense, the seedlings need to be carried out to prevent the seedlings from growing in length. When the seedlings grow to three true leaves, they should be divided into seedlings one by one, and the seedlings should be transplanted into the nutrient bowl. The temperature of the seedbeds is generally controlled at 8 to 20°C. Before the seedlings are planted, the seedlings can be cultivated at low temperature, and the amount of air is gradually increased. The minimum temperature of the seedbed can be gradually reduced to about 5°C, and the time for hardening the seedlings is about 1 week, and then the plants are planted according to the cultivation mode and weather conditions.
Intercropping of Spring Cabbage at the right time: 15 to 20 days before planting, in accordance with the width of 1.2 to 1.3 meters, the width of 40 centimeters in the middle and 30 centimeters in the depth of the ditch, will be placed on both sides of the excavated soil. 667m2 warms up about 4 kg of fermenting agent with gold treasure greenhouse, 40 kg of wheat bran or rice bran, uses straw, golden treasure microbial fertilizer and compound fertilizer, that is, uses the technical scheme of warming starter of ginseng greenhouse, which can increase the underground temperature of 20 centimeters. 4 ~ 6 °C, when the 5 cm soil temperature is stable above 5 °C, seedlings have 6 ~ 8 leaves, about 60d seedling age, can be planted. Colonization of planting spacing 30cm × 40cm, 667m2 colonization of 5000 ~ 5500, after planting should be irrigated in time.
