Cultivation of cumin in intercropping of wide-film pepper

Line pepper adopts wide film paving and intercropping cumin, the yield of line pepper remains stable, cumin also has a harvest, to achieve the goal of two harvests a year.

I. pre-broadcast preparation

1. Select a place

Choose autumn and winter irrigated land with good soil quality and soil moisture, and Gramineae crops are better in the previous crop.

two。 Seed preparation

The seeds of pepper in the front of sowing were soaked in 55-60 ℃ warm soup or mixed with 0.3% dimethazone to prevent rotten seeds and seedling diseases. Turpan large-grain cumin or Yanqi basin farm seeds were selected and selected with 10% salt water before sowing.

3. Apply sufficient base fertilizer

Combined with 667 square meters of irrigation in autumn and winter, 2 tons of farm manure was applied. After the soil was thawed in spring, 667 square meters of diammonium phosphate 10kg, urea 8kg, potassium sulfate 5kg, soil preparation reached the six-character standard.

Second, sowing requirements

1. time

The ground temperature of 10 cm is required to be stabilized at 12 ℃.

two。 Film mulching and sowing

Choose 1.45 meters wide film, mechanical tiling. Mechanical sowing of line pepper, 1 film 4 rows, row spacing 30 cm, plant spacing 9.8 cm, film spacing 40 cm, manual sowing cumin in the middle of 50 cm line spacing on the film, plant spacing 30 cm, seed 15 cm 20 seeds per hole, in order to grow into clusters.

III. Field management

1. Cumin

The seedlings should be released and fixed in time after emergence, leaving no less than 10 seedlings per hole until June harvest, without watering, foliar fertilizer can be sprayed, the mortality rate can be reduced in the later stage, and cumin grains are big and full.

two。 Line pepper

The seedlings were released in time after emergence, and the seedlings could be fixed with 3 or 4 leaves, with 1 plant in each hole and two plants in the absence of seedlings. Ploughing squatting seedlings, ploughing at least 2 or 3 times before head water, head water time is determined by soil moisture, push back as far as possible to facilitate squatting seedlings to develop strong seedlings. Uncover the film after the cumin harvest before the head water, combine with ploughing to open ditches and ridges to form double-row seedlings, the first water irrigates the horse water to prevent the pepper roots from flooding, and then irrigates according to the field capacity, and the water level is less than 8 cm from the border surface. The over-growing plot of the plant should be properly controlled. In the first inflorescence blooming period, 667 square meters should be sprayed with 2.5 grams of promethamine and 15 kilograms of water. During the formation of the third inflorescence, 667 square meters topdressing diammonium 1520 kg, using hole application or strip application. Spraying capsaicin and foliar fertilizer twice in full fruit stage, 4 grams of capsaicin + 20 grams of potassium dihydrogen phosphate + 100 grams of urea, and spraying plants with 20 kilograms of water are beneficial to flower and fruit protection. In order to reduce ineffective flowers and fruits, one more time was sprayed in the middle of August, 15 kg of water to 10 kg of dwarf. As a result, watering was controlled in the later stage, based on the principle of non-drought.

IV. Pest control

7. Insect pest

Mainly to control land tigers, in mid-May, before the third instar 667 square meters with 2.5% of the enemy to kill 20 milliliters; cotton insects control time from the end of June to mid-July, to treat early, small, treatment, alternate use of drugs.

two。 Disease

Pepper blight at the initial stage of spraying 25% metalaxyl or 64% alum 50 grams, 30 kg of water; virus disease in the initial stage of 667 square meters with virus A10 grams.
