Abstract
The rice-cultivating method in upland field includes seven steps of cultivating seedling, selecting field, land preparation and fertilizer application, transplanting, spike formation and maturing and harvesting, i,e, all the works of planting, field management and harvest can be implemented under the condition of upland field, and can produce high-yield high-quality rice.
Description
The present invention relates to a kind of rice cultivating method, exactly is a kind of rice transplanting dry farming cultivation method.
Paddy rice all is to plant in the paddy field a few days ago, and water consumption is big, and during the weather drought, rice seedling can not be planted on time, thereby influences output, moreover because the paddy rice seedling must be planted the paddy field, thereby limited the cultivated area of paddy rice.The paddy rice kind is poor in the paddy field ventilation and penetrating light, damage by disease and insect is many, and the fertilizer that applies easily loses with current, thereby output is unstable always, and is difficult to improve.
Used the rice dry-farming technology in most of area of China in recent years, but also there have been many deficiencies in these technology, it shows that mainly vegetative growth phase is short, yields poorly, and rice matter is poor.
Rice transplanting dry farming cultivation method is the breakthrough development to original dry farming cultivation method, large-area rice transplanting dry farming can greatly be alleviated human survival and plant needs contradiction between water and the growing natural drought, one hectare of transplanting dry farming rice will be economized on water 10,000 tons than paddy rice, rice transplanting dry farming can make planting grain not receive, planting the anhydrous water-deficient area of paddy rice and large stretch of middle-and-low-yielding fields thoroughly breaks away from the drought and waterlogging puzzlement and contributes a large amount of grains to people, the rice transplanting dry farming new technology can make the rice of the high yield and high quality that puts into production out of kind of corn, does not have paddy field also can plant paddy rice.
Rice transplanting dry farming cultivation method has mainly solved following problem:
1, solved the low and unstable present situation of middle-and-low-yielding fields grain yield.
2, solve easy waterlogging ground planting grain and do not received, planted the problem of paddy rice lack of water.
3, solved the problem of paddy field lack of water.
The objective of the invention is to provide a kind of paddy field that is suitable for low-lying land, easy waterlogging ground and lack of water, the output height, rice matter is good, technology advanced person's rice transplanting dry farming cultivation method.
The purpose of this utility model is achieved in that
Rice transplanting dry farming is meant at dry land water and waters rice cropping method under the condition, whole operations such as the kind of paddy rice, pipe, receipts are all carried out under the dry land condition in other words, and water water condition also just water cross the dry land water of doing on the land for building and water method, paddy rice is to produce rice plant below maxmun field capacity all the time, belong to drought and give birth to the ecotype, its concrete cultivation method is as follows:
Rice transplanting dry farming cultivation method by grow seedlings, select ground, site preparation and fertilization, transplant, go out fringe, seven steps such as ripe results finish.
1, seedling raising process:
(1) seeding quantity (kind of sprouting) is limited to 0.15kg/m
2
(2) moisture management: supporting root with few water is principle, controls the number of times that waters as far as possible, and watering then must be saturating.
(3) temperature treatment: stuffy in principle before 3 leaves, the back temperature of ventilating is let nature take its course.
2, choosing ground:
(1) physical features is smooth, subterranean water level is high, near apart from the water source,, watertight soil or low-lying land, easy waterlogging ground, non-black land can water or have also can unevenly of sprinkling irrigation condition.
(2) soil fertility is fertile, and unfertile land must be executed farmyard manure more and just can select for use.
(3) the light alkali ground of P in soil H value below 8, the meta-acid ground of pH value more than 5.
3, site preparation and fertilization: carry out generally that the autumn turns over or the spring is turned over (rotary tillage), the degree of depth of ploughing 18-20cm, plough the back in time rake press soil moisture conservation, convenient for pouring water, should do furrow, the wide 2-3 rice of furrow, smooth plot can be wideer again, the high 20cm in the furrow ridge, wide 30cm, furrow length is decided according to physical features, and is smooth in small, broken bits in the furrow, assurance is poured water convenient not towards seedling, and the guaranteeing of ridge culture get final product (the big ridge of 60-65cm) along corrugation irrigation with referring to dry land.For guaranteeing to obtain higher output, must use sufficient base manure, the one, dry farming nutrient easily imbalance is put in order and is run off, and the 2nd, fertile sufficient seedling shape can strengthen drought-resistant ability.Execute 5 tons of high-quality well-rotted farmyard manures for general every mu, when ploughing, apply, before transplanting with 15 kilograms of two ammoniums (or Nitrogen, Phosphorus and Potassium 25 kilograms), 15 kilograms in urea, 1.5 kilograms of biological potassium fertilizers, 2.5 kilograms in zinc sulphate, deep placement is gone in the 5-10cm soil layer, (as the increase and decrease as one feels fit of the visual soil fertility of the amount of spreading manure).
