Embodiment 1

[0044] In late April 2013, the number of pods on the February orchid increased, and the lawn trimmer was used to trim it. The height was 12-15cm. The side branches developed rapidly and the flowering gradually increased. As the temperature increased, the damage caused by the leafminer larvae gradually increased in late May. The ornamental value was lost, so the Er Yuelan straw was crushed with a stubble removal machine. The stubble removal machine was close to the ground, so weeds were also eliminated at the same time.

[0045] After June, the temperature gradually rises, dry and hot winds increase, only occasional sporadic rainfall, and the water content of the straw decreases rapidly. The temperature at 5cm of the soil is measured, and it is about 2 degrees higher than the open field in the morning and evening, but about 1 degree lower than the open field around noon. , the temperature in the open field is relatively stable. This is because the coverage of straw reduces the ...

Embodiment 2

[0051] In the spring of 2013, seedlings Baila were planted, with a row spacing of 2m*6m. No crops were planted between the rows that year, and a large number of weeds grew. From May to June, stubble removal machines were used to crush the weeds 3 times, rotary tillage 2 times, and suppression and harrowing once. . On July 10, Henggu No. 13 was sowed in the rain, and a large number of monocotyledonous weeds began to grow after 1 week. Because of the high density and more rain, in order to avoid grass shortage, it was treated once in advance with 50ml / mu of net catch (because The weeds are small, so 1 / 2 of the normal concentration was used). After 5 days, most of the weeds died, and the growth of millet gradually became normal. After 10 days, a large number of weeds were unearthed again. According to the forecast, there may be continuous heavy rainfall, so the whole field was sprayed with "Nabujing" (100ml / mu) + "Dimethyltetrachlorosodium" (150g / mu) with a sprayer. Water 30kg / m...

Abstract

A rainfed and minimal or no-tillage combined planting method for millet and orychophragmus violaceus belongs to the technical field of agricultural planting. The method adopts a combined planting of millet and orychophragmus violaceus, and comprises the following steps: first adding nitrogen fertilizers again to the millet 10-15 days before earing, planting orychophragmus violaceus between rows of millet, and spraying cut-up straw to fields after millet harvests; then trimming branches of orchophragmus violaceus to a height of 10-15 cm before fruiting of the growing orchophragmus violaceus in May of the next year, smashing the orchophragmus violaceus straw and doing stubble cleaning in late May, and sowing millet straightly with rain between late June and early July, not performing tilling of the field for 3-4 years during alternate planting of millet and orchophragmus violaceus. The method has the advantages of no operations of tilling, pushing and plough, and time and labour saving, and is a beneficial experiment of agricultural sustainable development under circumstances of 'no plough for one season, rain-feeding for one season' in limited mining districts of underground water, taking account of millet yields and ecotourism.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to a method for less-tillage and no-tillage planting, in particular to a method for planting millet and February orchid with less rain and no-tillage. The operation of plowing, plowing, and rotary plowing is simple, time-saving and labor-saving, and it takes into account the production of millet and ecological sightseeing. Useful to explore. Background technique [0002] Millet is a characteristic crop in my country, which has the characteristics of drought resistance and barrenness. It is one of the important food crops in northern my country, and its total output accounts for more than 80% of the world. At present, the national cultivation area is about 21 million mu, with an annual output of 2.7-4.5 million tons, and the planting area in Hebei Province is about 3.5 million mu, of which Heilonggang area is the traditional dominant planting area. [0003] With the inc...
