No-tillage interplanting model of shallow lotus root

The traditional one-year cultivation of shallow lotus root field affects the improvement of economic benefit because of the low utilization rate of land, temperature and light resources. In recent years, Suining County, Hunan Province has made great efforts to promote the no-tillage three-dimensional planting model of shallow lotus root. Generally, each technology can increase the benefit by 300 yuan per mu, and the high one can reach 1600 yuan. The six three-dimensional planting modes are introduced as follows.

Shallow water lotus root-- Chinese cabbage

After being dehydrated in shallow lotus root field for 5 days, Chinese cabbage varieties such as April slow and early ripening No. 5 were sown evenly and 0.5 kg per mu. Pakchoi was applied once in the third leaf stage of pakchoi. Pakchoi was harvested in mid-late December and the yield per mu could reach about 2000 kg.

Shallow lotus root-spinach

After the shallow lotus root field was dehydrated, the broken-beaked spinach seeds were sown about 4 kg per mu immediately, and the thin human feces and urine were poured once after emergence, and the combination of big water and small fertilizer was applied frequently in drought. Spinach was harvested in late December, and the yield per mu was about 1000 kg.

Shallow water lotus root-- coriander

After dehydration in the shallow lotus root field, about 2 kg of coriander (also known as coriander) seeds were sown per mu after kneading on hard ground, and then trampled with their feet immediately after sowing. 500 kg of thin human feces and urine per mu were applied after emergence for a total of 2 Mol 3 times, and the leaf surface was sprayed with "920" once in late November. Coriander was harvested in mid-December with a yield of 800m / mu and 1000kg / mu.

Shallow lotus root-mustard

After being dehydrated in the shallow lotus root field for 5 days, the mustard seeds were uniformly sown with about 0.5 kg per mu. After sowing, gently step on the seeds to make the seeds closely combine with the soil. Thin fecal water was applied once 10 days after emergence, and once again in mid-late November. Mustard tea was harvested in mid-late December, with a yield of about 1400 kilograms per mu.

Rape-shallow lotus root

Rape seedlings were sown and cultivated in early September. After applying sufficient basal fertilizer in late October, rape seedlings were planted according to the row spacing of 50 cm × 30 cm. After rape is planted, the lotus root seed is buried in the soil 6 cm deep according to the density of 1 bud per square meter. Rape is harvested in the middle of May the following year. Pay attention not to damage the leaves of the unearthed shallow lotus root during harvest, and immediately put the shallow water layer in the field after harvest. Fertilize 3 times later, applying about 1500 kg of rotten organic fertilizer per mu.

Shallow water lotus root-rice seedling

In mid-late April, 5000 kg of organic fertilizer was applied per mu, which was formed into a high border 1.2m wide. The lotus root seed was buried in the soil with a depth of about 5cm to flatten the border surface. The germinated rice seeds were evenly sown on the border in the first ten days of May, and the seedlings were transplanted in early June, and about 15kg of ternary compound fertilizer per mu was planted. When adopting the above six techniques, we should pay attention to the following three points: ① shallow water lotus root field should not cut off water too early, otherwise the yield of fresh lotus root and the time of water cut-off should be controlled in the first and middle of October. ② shallow water lotus root interplanting vegetables, such as insufficient soil moisture, should be irrigated to create soil moisture. ③ leafy vegetables have no fixed harvest standard, so we should pay close attention to the market situation and harvest and sell them at the right time.
