How to interplant mountain rice under oil tea forest?

Because Camellia oleifera afforestation is cultivated according to a single pure forest model, the land utilization rate is not high, the woodland productivity is low, and it takes 5 years for Camellia oleifera to have a certain yield, the early capital investment is large and the economic benefit is slow, which restricts the development of Camellia oleifera industry. For this reason, all localities are actively exploring the economic development model under Camellia oleifera forest, especially through reasonable interplanting, it can not only increase the income of interplanting crops, but also "ploughing instead of caressing", improve the growth environment of Camellia oleifera and improve the economic benefits. How to interplant mountain rice under the Camellia oleifera forest?

Mountain rice, also known as upland rice, mountain grass or dry valley, belongs to the ecological crop of dry farming, which has the characteristics of strong drought tolerance, good barren tolerance, strong stress resistance and wide adaptability. Mountain rice belongs to the nature of glutinous rice, the rice quality is in line with the first-class standard of high-quality rice, no chemical fertilizers, no pesticides, natural growth of pollution-free organic food.

1. Camellia oleifera stand selection.

The newly-built Camellia oleifera bases are generally located on low hills and gentle slopes below 800m above sea level and slope below 25 °, with row spacing of 2.5mX3m, and equipped with perfect infrastructure such as operation path and pool. These newly-built Camellia oleifera bases can be used for interplanting mountain rice.

2. Key techniques of interplanting mountain rice in Camellia oleifera young forest.

(1) selection of species

Bailing Valley No. 5, a japonica type, beige white, strong drought resistance, like stony loam, resistant to barren.

(2) sowing

Mountain rice should be planted immediately after soil preparation and fertilization. Generally, there are no weeds and shrubs in Camellia oleifera forest through full reclamation from early May to early June. Combined with comprehensive soil preparation, digging holes to apply base fertilizer, the amount of fertilizer per mu is organic fertilizer 1000kg, compound fertilizer 10kg. Digging the hole should be shallow and the depth of the hole should be 3~5cm. The sowing hole is more than 60cm around Camellia oleifera, the fertilizer and seed in the hole should be separated as far as possible, the plant row spacing 40cmX45cm, and the seed amount of bailing Valley No. 5 2~2.5kg per mu.

(3) Daily management

The mountain rice sprouted about 10 days after sowing, and the seedlings should be loosened and weeded in time 25-30 days after they were unearthed. This is the time when weeds grow most vigorously, and the weather is the season of plum rain. The timing of weeding is not good, which will affect the growth and yield of mountain rice. At the same time, if missing seedlings are found during this period, densification and thinning can be carried out on cloudy and rainy days.

(4) Prevention of diseases, pests and animals

In July and August, high temperature and humidity, diseases are easy to occur, pay attention to monitoring work, the two varieties introduced in the growth period did not occur diseases and insect pests, but animal pests often occur. When the mountain rice seedlings were first unearthed in May and June, the Camellia oleifera forest had just passed the full reclamation, and there was nothing else except the newly unearthed mountain rice seedlings and young weeds. It just so happens that wild rabbits like this kind of environmental activity most; in August and September, when the mountain rice began to mature, the wild boar came to "rush to harvest".

(5) harvesting

The mountain rice stalk is tall and is easy to lodge after maturity. It was harvested in late October, threshing the rice panicle, and then chopping the rice stalk back to the ground.
